Hi Hello, good evening, good evening, good evening everyone hello hello hello yes good Evening good evening good evening everyone Hello Hello Hello First of all tell me this Do you all hear my voice correctly? can you hear me namaste namaste jai Shri Krishna Radhe Radhe Ram Ram Bhai Sarne Come quickly to class, yes come come Come enter my painters yes good evening good evening good evening many All the enter punters are gathering okay Yes, the date notification for all of you people I hope it has reached all of you. It must be that the date has changed, right? All the people from the 27th we from the 27th It must be going on, okay, so a little bit You have time left and you have more meaning in it. Maybe a little for many children And stress increases, sir, please end this. It is happening quickly, isn't it, it is happening due to anxiety? But utilize yourself well. please do the time yes yes yes good evening good Evening Namaste Namaste Namaste Love You All Love You all love you all come quickly son yes and Today we are going to do a slightly heavy chapter. are optical instruments separated I have given that the remaining chapter is also very heavy. yes we have a lady chapter okay end I know that all of you are very ladies All the children are troubled by the classes, early Tell me, can you all hear the voice correctly? I can hear it, yes I am very scared I laugh whenever a child says something like this. I was feeling very scared, son, so I had to study. No, when I had to study, there was a lot of nonsense. Yes sir and today when the voice is coming properly very good very good very good okay and today when The time has come, but I am still scared. The rest of the time is more important. If so, do it, no problem. Yes, yes, yes, yes, I am feeling stressed and scared. Sir how many marks are you getting Son, study all these questions. Nothing is going to happen, yes now the last It's a moment now, you can't even say that. Sir can I start from here na na na This is the end, yes this is the end, okay Yes, there is a comma after it, basically not the end. Yes, I have just done JE Mains 2, okay yes. All the hunter punters are gone, okay so is mine My name is Rajan Singh and I welcome you all. I do it in this Manzil series and this time we People who are going to do that is Ray Optics You all know it's quite heavy. This is a big chapter, okay, so this We are going to do it in one short. I have a lot of topics, okay, yes, no. If you want to start, you can do it. But this is not the time to start So, okay, what do we have to do? Reflection from plane mirror spherical Mirror Refractors of Light Ti R Prism Refracted from spherical surfaces, thin Lenssex is a very big chapter, I want to say this If I say so, now many children We are fine, yes, yes, yes, what will be the duration? Now many children like this, you guys tell me. what should be the duration ok just this You should also see that some children will say Sir, 5 minutes. Please teach me, it is more important. So we don't have time, we are very busy. ok what is the duration according to you should go okay Yes, son, slap the corpse twice 24 hours a day. Or hit five, it's equal, okay, so 10. After an hour, you all would have become corpses. If so, there's no benefit from that, right? 12 plus good good good give yourself now I will go to sleep after an hour, yes, go to sleep yourself Let the teacher go and teach here for 12 hours. They should enjoy it Yes, in reality we have to approximate this We should finish in 8 hours. okay sen to 8 ars because after this The story does not end there, If the teacher keeps teaching, you will get a rank, right? If you don't want to study, it's okay, then seven to eight hours. I am taking the target, okay we Okay, 7 to 8, now that's up to you guys. It depends on how you behave. okay now one for all of you guys A lot of good things have also come along in the past. There was a big problem when we used to conduct polls. It used to be so now we have a tech team It's okay Techno guys, you work hard day and night You came up with a very good product I mean, if you're a little picky, You will find this very dangerous. The product is fine, which we call a pole. Now You must have seen in youtube classes which We have poles just like that. But this is a slightly Supreme version, okay? so how to answer okay i will answer first I will tell you because in the end the leader We will also look at the board, okay leader. How many answers did you give in total on the board? Whose accuracy has been higher, that is us People will see that even if the average time comes, then Lappa no need to kill okay in this first Writing ABCD in the chat to answer For kids like you, we have the right to write a poll. It used to happen that I would have come to your side. Nothing like this will happen here, okay? You have to write your ABCD in the chat like Let's take a pole as an example, okay? Yes very good very good okay so take the poll Let's take it as if we've made a start I have done the poll, now you can do it as per your wish. B CD A B CD Whatever you write, whichever is first once you'll write okay now suppose first You wrote A and did the calculation after some time Then your answer came, I tried for a little while more. So D came and then if I did more then B also came and If you tried a little harder, you would have found out. This topic was not with real life like you It will turn out that it is not according to It's okay, oh my god, the child Friend, I had marked A earlier but now If you have done it with hard work then answer C will be correct. There is nothing like that when you give the first answer I will mark it as ok yes this is the probability and permutation goes into combination okay Yes, if you take out the red ball or yellow ball then the answer is We are very fast, the answer match has been done. Then after a while, look, think about it. He also had blue hair, I didn't even take it. Then do that too after some time. I found out that the question was not about probability. there was something else okay red ball yellow ball blue You have done permutation and combination just by looking at the ball. I started applying, the question was something else. So the first time you mark it, okay, which Also in your chat you can write a capital letter once. Write in small A A A A A A Write like this, now someone will be very fast brother, I I will not fool this computer AAAAAAA If I write B also then he will not take the answer, okay? Yes, if you think too much about it, it will make your mind go crazy. You will do it, he will not do anything, this is fine, that answer I will not take it, okay, so let's say Chat our poll stopped I did all Children are writing A answer, so I wrote A answer. Mark it, the time lag is very less in this This is 80% of our Indian options. If you are telling the pass here then the leader board also We will have Lappu Baj who is here Look brother, yes this is today's Lappu Sakshi, it's okay, he has asked brother Sir, what did you say, okay, he got A1 There should be so many racers in India, man. There are strong kids with great reaction times. We are forcibly the same story, isn't it fish? Reaction time is teaching to climb trees He is very strong brother, he is very strong Yes, what did you say, okay, so this is the reaction. With time, another one will come to us. There is something special about it, okay, let me tell you. I hope you get benefit from this Unity of lecture I think I spelling I am writing it correctly, okay, D Pad When you go to life, okay, you will once If you register, whatever lecture you have read I have seen PW's only okay that's You will go and in this chat you will do one thing You will see that this will also be magic for you people. Exclamatory Mark Exclamatory Mark If you have doubt by doing I am writing it now with the tech team. two minutes and then yes two minutes and then I talk I will do it, okay, let's write our doubts or else When you write doubt, write an exclamation mark. After this, if you do it by writing doubt then Whatever doubts you have here, they will be with me. you will keep coming here okay so you Write an exclamation mark and express your doubt and Then you have to write doubt, oh yes, okay and one By marking an exclamation mark By marking notes or exclamation marks Note: If you write, that time stamp With this you will be saved on your paid life. Yes, now when the tech team was telling you I said, Sir, tell me one thing I have a doubt about. What is the spelling, he obviously It is true, I said it but you It seems our child will be able to learn this doubt. Our children, brother, I try and I had read in Lakshya that the children had doubts. I used to write the spelling 'y', I said add this too. This also becomes a doubt for those who have done it and For some children, this would have been a doubt. And some are very fast and dangerous. If he has any doubt, he clears it out, Sir. It has come, I said add these also The children will benefit, right? The spelling of doubt, son, is this if you If you write this then your doubt will come here if you If you keep talking all this, he will go away straight away. The English teacher is fine and A message will go to your father that the child Don't stop studying, it's done in 12 years. It has been proven that he will not be able to do it, okay? So if you write all this then the opposite message will be sent Will go to the parents too much Technology was put in Yes, they have become stubborn, so you can do these things Additional here you can clear yes Like if you people write some doubt and post it Look, Samarth has written hi, it is itchy. There is this body itch, isn't it? No, they are itching for technology, they saw that Let's try selling it, Samarth sent a high Yes, very good, okay, yes, now other children too. Before we start sending, we Let's come here, okay, let's go brother, okay. yes yes they have doubts Hi, okay, so this is the story, son, now all Kids, be serious, okay, yes everyone. Baby, Seriously, Seriously, I've given you all I have told you the features so that you also know about them. Some benefits if PW's team you Even if she is doing it for free for the people So many features brother to do this thing too much technology Requirements cost a lot It also happens if free for students too PW is doing this, it's a big deal. Yes, it is fine and there should be such a short time lag brother. When you were telling me, I felt goosebumps. The bombs were coming, I said take so little time How are you doing? Are you fine? Yes, these are small things. No problem, salute to the tech guys. Yes, come on brother, let's start now. okay so what is ray optics Approximately you may get two questions Well sometimes if you look at the whole optics If we talk about it, you have a couple of questions. I have a tendency to meet you now Sir, two questions. So much hard work for son two questions if you If you don't do it, you will be left behind by thousands of people. It is important to go, easy questions are also coming Yes, medium is also coming, tough is also coming And after this, the children who clear Advance If you do it, then its basics are also clear. should be okay yes yes come come come Now all the children, please pay attention here. we'll see first thing okay yes all the kids We'll just look carefully here, whatever this This is a lecture, okay, you will get full information in it. Benefit from listening with concentration It would be okay if you said no, friend, this Things come, I leave these things behind I will give you these things sir and teach them in depth. That thing will not happen, I will decide that this How deep should the thing be taken? Obviously, we have less time. If you have exams during the day then Main We have to revise some important things. Questions we must see That's the Man Purpose of the Manzil series right to now all Children, please pay attention here. The first one we have is what I'll tell you about. I will give it to you, okay, keep making up your mind, whatever you want You can recall things we've done before. we'll talk about mirrors okay If questions arise on this too, then be careful. See, we never have any light anywhere. When the surface falls, you will experience three phenomena. People know that there is a bouncing back of light which is called We have one reflection Absorption which is not in our syllabus And thirdly we have refract or Bending of light whenever it is through a medium enters us in another medium Okay, so if we first Talk about reflection bouncing back off Talk of light Make the main points in your short notes. Son, well, if our If any light comes near and falls on the surface okay so the light that's coming to us This is called incident where light This is called point of falling Incidents are what you make normal for many of us. have brave children who make it normal Ray says no this is called normal and This is your reflected ray okay short Keep making notes, son, whatever work is needed. There are things that reflect light at whatever angle you measure it. They always measure against normal, this is Your angle of incidence and this is your angle of reflection so the first law is that if you If we talk then we have incident re Normal and refracted rays The reflected ray lies in the same plane or Let's bring it on the plane, son, whatever it means able to think mathematically, that means The volume should be zero, right, if anyone If we plot three vectors we have a plane If you used to come in then you can get the box product at zero If I give these in vector form If I give it to you, then you should reduce their volume to zero. You may need to take care of this thing and Secondly, the angle of incidence is for you. Equal to angle of reflection is always our Stays close, is it clear, all the children, yes And no, okay, we Clear Clear will run from the very basics Be careful son, don't do it forcefully. Don't do it forcefully, listen carefully. It remains with us, even if we have the surface. We should have regular sir, regular means Smooth or diffused Yes, diffuse means rough surface. Why not, it is okay whether it is a rough surface or We should have smooth surfaces in both Laws are applicable Laws are applicable these We have lodges that are always applicable. Okay, tell all the kids this now. Tell me honestly that this law has a vector There used to be a form, what was it, all the children Vector Form of law of reflection in vector form Who knows what happened to it? Many children are probably studying for CBSE. They might not have noticed this thing. who will be the target students or Students of Prayas will have heard this thing must have also driven it, all right Children, tell me quickly the vector form of yes What the lodge says we have in vector form Who remembers that incident? The eye cap which is reflected Cap means talk direction wise plus t Voice of Odds a in n cap it This is yours, we have it, very good Very good, love you son, please be serious. Son, it's okay sir, is this important? Yes. it is important yes it is Important okay so vector form of laws what does the reflection say sir what is this Direction of incident, I will write it here. Your short notes should contain Direction of Incident Ray Direction of Reflected Re Theek Hai and Direction of normal okay we have this between us are related in a certain way and we call it People call it the vector form of Ohm's law. The vector form of the law of reflection Note it down in clear very good notes Many children have done it, very good, it is fine now. When it comes to plane mirrors, we have Now we have a plane mirror. that's okay Listen carefully what is a plane mirror you took the glass okay you took the glass And behind this glass you have reflections Material applied This is your plane mirror Remember its important points. what were near okay whenever you any First, carefully understand the object. Important point that if one of your objects at any distance x okay so always An image of this will be formed at the same distance x. Your image will be formed at the same distance x All the children give thumbs up at this point. Please son, be serious, see friend last I don't have any direction for you at this moment. You should be serious, this is your I know there are many responsibilities The children will run away but I will remain as long as I can Meaning, I want to intentionally teach them Serious children who are really revitalized I want to do it okay yes very good Joe The object distance will always be the image Distance is equal to Sir Ray Diagram There is absolutely no need to make this I have written the points here. Distance is equal to object distance We have this object for you right now. Even if yours is extended, it's fine. Even if your object is extended Your extended It will be made, okay, we have the image of the image. Distance is equal to once I write this I'll take it and then you put it in your notes. is equal to object distance son okay we have the size of the image is Equal to the size of your image Son, that is equal to the size of the object. is equal to the size of the object We will have the same size of the image as well. It happens, okay, this has also come, that means if Its height of the object is then its height of The image will come and I am saying here the height The value of the off object is the same as the height of the off The value of the image also remains with us. Clear very good love you son ok The next important point is that if our Listen to the meditation next to the ok important Point we have object and object End Image R Always are always of opposite nature always of opposite What do you mean by saying nature, sir, plain For the mirror, if I talk, the plane Son in the mirror, if suppose plane mirror We have it ok if your object It is real if your object of attention is real Son, if it's okay then its If you were to draw a diagram, it would be like this and like this There is no two reflected rays. Remember the intersection, okay, the image is yours. What is the intersection of R Rs Intersection of reflected rays is yours The image is there and the object is what you Son, this will be useful later, please revise it. keep doing this is intersection The intersection of the incident rays is that your object is clear so if you If you look at this, this is also your RR, this also Your RR is if you extend them Then you will get the image, look carefully If you have forcibly extended it then this Yours is virtual son, okay, it's forced. If you have done Intersect then this is Virtual and incident race if you Speaking of intersections, this is your Real If you look at the object, it's the opposite of this. Suppose I have a plane mirror like this and the light is coming to me like this attention See if the light is coming to me like this You all can tell that here sir Incident is rage If this is incident rage then what is its There will be an intersection, sir, if it comes here, then this will Be your object sir and if you see You are forced to make an intersection If so, your virtual Object clear all children very good love you son And this is after your light reflects. Here goes the riff of the reflected race If you look at the intersection of RRs If you see the intersection, son, it will be yours. image and the image we have will be real because The Real Intersection is coming to us clear Clear Clear All the children Yes and No Attention Listen to this chapter from your son, if you read it yourself I am saying revise every time with the teacher This is at least the benefit of revising Main important points in time you We revise it if you do it yourself. So many times you put energy on that thing There are people whose requirements are more All the things I see on the boards I'll tell you, you just have to listen and I have to do it with the question, clear, very good. So this is what it means to say opposite nature, sir. Meaning if this is real then this is virtual If it's virtual, we'll have it. Real becomes the second important point okay What is the third important point that we have? Is Son, this is a literally inverted image with us. would have Okay, literally inverted, we have the image. She will say that it means that if we pay attention From It's okay to check if an object is such that And if we have an object such that So what was its object distance? It was So according to this object distance, An image will be created here and its Object distance son, this was his According to the image distance, we have some such If a pass image is formed then the object which is yours If it is inclined in this direction, the image Yours remains inclined in this direction This is called Lateral Evers Clear Clear All the series kids once dil bana Give me love you all son, love you all, is it okay? You are understanding lateral inversion in this You may also have noticed clock problems. Sir, tell me what were the clock problems? gives Yes, okay, you have set your clock in this. You must have seen problems too, Sir Clock. What happens in problems is that if the value I have a mirror, okay? let's say I have a mirror okay and Here's a clock I made for you Such a time appeared okay so in the real world you We know that we have this real thing, so in this It must be three o'clock, so what's left in the image? Hoga This Is Your object okay and this your image so image How will it be for you, son? If it is something like this, How much should your phone be ringing in the image? It might not be ringing. will be very good okay in image world Yours Joe hoga image me aapka na baj raha This will be your answer, isn't it? The question is here. How does it get complicated? Let's say I have an example I have given you that we have a clock Whatever time we have, we suppose 850 okay suppose I gave 850 like this Telling you how long the image will take This is the image showing how much time you will get. If you want to tell me, then the concept is very good. Very good there is a child Anonymous he very I gave the correct answer that Sir, if I see the image If you want to calculate the time, you have to subtract 12. Doing It Actually Makes You 12 Out of 12 By doing my 3 you got the answer yes then you How will you do this in 11 hours and 60 minutes? Only 12 is written son because 60 minutes is one minute. An hour will make mine 850 if you talk If you do, you will get your time You will get your time if you do this Let me give you another example for a few seconds. If we talk about our time on the clock Tha that is 5 20 and 35 seconds we have If so, how much is in the image? If you want to remove the image then So if you want to subtract 12 then you can do this how to write You subtract 11 from 59 and 60 seconds. If you give 5, 20 and 35, you will get this answer. Is the concept clear or not? Neither do you have any questions on lateral eversion. can you sir how is this 12 written as 60 Seconds make a minute, so you can convert it to zero. If you do then 59 + 1 60 minutes makes NR So it is written as 12 only, I have cleared it. Very good, very good, okay, so there we have it. If she lives, I have written the image Distance is equal to object distance The nature of the image is opposite to that of Object and Image is Literally Inverted Is it clear yes or no mathematically? Let me tell you one more thing here. Many children will be able to understand this thing, okay Maths because all of you are very smart You guys have done such high level math. mirror plane mirror is a Perpendicular bisector plane Mirror is perpendicular Bisector This is a perpendicular bisector Two Line Joining Dil Bana Ha Ya Na To line Joining Object and Image Are you my All children agree with this once heart Make it yes or no if I Let me give the coordinates x x1 y1 and its If I give the coordinates x2 y2 then this is the mirror wala point you mid point very good mid You can also calculate it using the point formula. Or where is your mirror if you I know its coordinates, okay, if you I know its coordinates. I know its coordinates. If you know then you can also talk about its coordinates. a little bit mathematically you can Understanding things clearly Love you son okay Now the motion of the object so before I I will talk about rotation of the object. I will question everything, look carefully. You have to revise these important points All right, all the children, please watch this. So, suppose I have a plane mirror Now you tell me the answer, okay, if I agree I have a plain mirror, case one. My case one is that the object is rotated object is rotated I rotated the object So what impact will it have on the image if Suppose the mirror was my object, son. Here it is at some distance, so yes or no Tell me sir if the object is this So at the same distance, somewhere or the other, the image made of it Hogi Yes 2 Theta saying wrong wrong wrong question mine is this if I rotate the object If I am thinking about where the image should go Tell me I've placed the object here at theta If rotated by an angle, the image will move upwards. Should I go down or should I think about it and tell me Very good, first time telling me literally I am feeling very good even though the kids are less But the seriousness that is coming in the chat Thanks to the team if he is useless from behind My efficiency is deleting messages. It's growing, I don't know, I feel good from inside I want to explain things more in depth, okay? I love you all son, please remain serious like this. If you maintain it, I will try. Stay in the shortest possible time because it is the last Then your saturation comes, so you start doing things You won't understand thin If there is a lensation then till the end it is for us It is important, okay, some children will say sir Hey crazy, we have Object Distance Is Always Equal to Image Distance if your object is here The image will also remain here, friend, how can it remain here? will go right so this image here also Theta angle is rotated carefully See how much it has rotated It has rotated to us so if you See, this is new object and this is New Image Clear then Image Rotates Concept What it does is that it rotates image by image rotates by the same angle in opposite sense in opposite sense all Children, please note down this concept. I will question you on this now if you If it is rotated by 30°, it also turns by 30° It will rotate, it will not go up, it will rotate here if If we look at it anticlockwise then it Clockwise is clear in the opposite sense very Good very good, okay sir, if I look at the mirror If I turn you around, look carefully in the mirror. Case to Hai Beta Mirror Is rotated mirror is Rotated if you rotate a mirror So I'm going to ask you a question first, okay? Because children get doubts here. Okay, so let's say I had this. mirror okay I had this mirror and whatever Your object is at a distance, son. But here you had an object, so one Your image Bunny Clear Yes Very Good Very Good Love You Son, if I turn the mirror this way now By theta, I assume Take the mirror, okay, this is your son, the mirror. Okay, this was your mirror, I used this mirror what has been done by rotating it by theta angle Diya, okay, this was your original position. I rotated this mirror by an angle theta So you also know that was normal for it. Earlier this was the direction of normal, right? Normally yours will turn around like this from here also Will Be the New Normal is fine, this is your new normal. This also rotates by theta angle. yes or No, very good, very good, love you son, it's okay If you are rotating the mirror then now whatever Your light was also going off at this angle. If the incidence is theta then the angle of reflection is So this is also from theta angle. This way Remember, the image is the intersection of R Aras wherever reflected rays meet If it comes there then there should be an image somewhere. may be here, here, here, here, here Wherever it is, it will remain on this line. The original position of the image is It was and finally your image came here so what You understand that my entry has many The children are also answering, Sir, this is 2 theta. So this will be 2 theta Very good, so remember that if the concept is yours What if the mirror is rotated by Theta mirror is rotated by theta image Rotates Those who are not able to understand even from the diagram No, the concept has to be understood, the image rotates By image rotates by 2 theta these two two These will rotate by 100° angle See the sense if you turn the mirror clockwise If rotated, the image also rotated clockwise. If this was clockwise, son, then this is also yours. It has come to us in a clockwise sense only So 2 theta in the same sense we have this The concept remains clear, is it all? Children, yes and no, are we clear? Is it so? Yes sir, if I go anticlockwise. If it rotates, it will also rotate anticlockwise. Clearly, this important thing revolves around Points to be in your short notes I want your son If it is JE Mains 2 then you should not think that brother You are reading a long chapter again, by the way. Main points and questions straight away love you son Now a lot of questions come up on this as well. Now to understand this you must carefully Can understand mathematically also but the concept What if you stand near the mirror, suppose I There are four cases here. But okay, four, we have cases, a mirror. These There is a mirror, this is a mirror we have. okay and we have a mirror There will be many of you children like this. who never once saw ray optics I agree you might have read it, but at least After doing this, if you feel a little If you think about things conceptually, you It will seem easy, that fear will go away because I too attempted JE for the first time. If I had given it to you, I would have left Ray Optics and even Release into ray optics even in the second turn I was told that I am not that tough for you, I am a JE. I will show you the recent Mains questions. That's also from the ray diagram, so if your My temperament is right, my friend. If you want to take maximum marks then you Definitely you will score well from here. Suppose I have a mirror resting on me right now. I understand that if my object here is 2 Try going from meter to second like this this is the velocity of the object perpendicular to the mirror listen carefully so you can you tell me that sir, its a The image will be where the image will be going left Or right common sense thinking this is exactly this You absolutely have proper common sense. If you listen carefully, you will automatically learn many things. You must have placed your hand on the glass. If you look at the glass, If you are going towards this direction at some speed then the image Many children wonder where she might be going, sir. If it is going this way then it will go this way, thank you. God, I have a lot of logical thinking. Sir, the image should go here, why? Because object distance is always equal to image distance if object distance If it is less then the image distance will also be less, remember Keeping the velocity of the image perpendicular to Mirror, this value wise remains the same with us. So the concept is if the velocity of image Perpendicular to mirror has to be removed, this is Negative of velocity of object Perpendicular to mirror sir what is he saying This is saying if I move from 2 meters per second If I go here, it will move from 2 meters per second to here. Sir, if I move from 10 meters per second to here If I go, this is 10 meters per second from here. Sir, if I move from 5 meters per second to here If I go, I will go here at 5 meters per second. Clear, clear, very good, now take a look. Second case we still have the glass on the rest I am taking it, those who have this doubt, sir, if both We will also talk about what will happen if it goes away. Okay, if we have the mirror right now at rest. This is your object, this is going like this velocity of object parallel to Can you tell me if the mirror is okay? where is your image going to go, up or Tell me up or down, tell me very good sir If the object moves up, the image will also move up. If you go in front of the mirror with a pen If you have taken it up, then at the same time its image also It goes very well so you will stay here Velocity of image parallel to mirror is ok So sir what is the concept of these two will always remain equal then the velocity of image Parallel to mirror is nothing but velocity of Object to Mirror It is always value wise your beans live will go up okay very Good Sir if I rest the object this time But I am keeping these two cases separately. If you take it, there will be space to explain the case. to okay case to we have object at rest hai thik hai and mirror is Moving son will just present all the things You have to give time as it happens I will explain everything in depth. listen carefully, suppose that my Pass now on object rest Okay, and my mirror, this is moving parallel to its own velocity of Mirror Parallel To Mirror ok is velocity of mirror parallel to Think about the impact the mirror will have and tell me. I'm standing, someone is coming with a mirror. And if he takes you away like this then you will lose your image. Will it be visible, will it be moving or not? No effect, whatever your image will be Son, whatever your image may be, it will be at rest. If it remains then do not believe that Sir finally will stop no impact no impact on no Impact on velocity of No one can give you an image at the velocity of the image The impact is not to be taken directly Talk no impact if I stay I would stay still even if I was walking, so image According to me, something made of glass must be moving. not going to impact Clear sir, all this is for mains, son. Clear your doubts now, the exam is after 10 days. Obviously, I am for 10th class. So I am not teaching, right, the JE type. There is a channel, you have read the name too, right? Son, put aside all the unnecessary questions and learn something. You will find another one here where children have doubts. Let's say I have a mirror okay I have a mirror this is my have an object and the object is now If I am assuming I am at rest then yes it is a thing An image of this If we have it moving Velocity of mirror perpendicular to mirror Okay, now what will be the impact? Children, tell me what impact will it have now? Children tell me, some children call it twee. Some children say v in it relative Some children introduce the concept of velocity. Let me look carefully my friend, my simple It is true that the farther the object is, the more The image will be far away when this mirror is here But you must have come to see this object after thinking about it. This mirror of yours is stuck, son. If Guess it's come this far Where would the image have come near you or it has already come? It must be so, how far would the image have reached here? It must have come by now It's okay to see, very good, very good, so this Notice if this mirror has this X If it was distance, son, then this was also ex-distance. This mirror has moved x in time so Its velocity was how much this image moved In that time, 2 are one, so it The velocity should be doubled, yes or no Very good, so you can say that we have The concept is that the image moves with the image. Questions have come in moves with 2v Velocity with respect to ground With respect to the ground Respect to the ground if you talk okay with respect to the ground in the same Direction of mirror in the same direction of The direction in which you hold the mirror Your image will also go in the same direction. Will it move? Is it clear? Yes or No, yes, and no, now many times relative velocity. The question of velocity of image comes with How much respect to the mirror would there be if this happened If the question comes then 11th class relative Putting the velocity v = va-vb Easy question will be Clear very good so what did I say that If the mirror has moved x, the image mirror will be here From here it took x time to travel, so from here it If 2 of them run in the same time then if Its velocity was then the velocity of the image Hogi with respect to ground clear Very good, very good. Now here's a problem. Many children feel that Sir Vat is Both are moving, take an example Let's say I have a mirror. okay and one we have the object traveling at a speed of 5 meters per second within angle of 53 degrees and this is going Vitra meter per second at an angle of 45 Degree find the velocity all the kids do Tell us the velocity of the image All the children are with respect to the ground Let us now pose this question Clearly, all the children are walking now, sir. Yes, this is irritating me sir. You don't have to worry, okay, what are you doing? Son, first of all we will do all the velocities Resolve if you look here Your 5 cos 53 will come then this will be the And this will be four and this will come to your table. And this will be to Ya Ya No, yes, I love you son, okay, just look at it. Your image will appear if this is your object So definitely one image would be listening comfortably. Many children are responding to the impact. Okay, let's take it one by one. My object is moving in this direction. So you get I cap minus I cap J cap and Answering in minus h caps if object If the velocity of the image is 3 ah cap, then What will be the velocity, we will do it comfortably No problem, take it easy if If the velocity of the object is 3 @ cap then the image Think and tell me what the velocity will be. Very Good some kids say sir three then back Whatever I told you, you would have done it all in vain. If the object is moving here then the image If it goes here, it will be in this direction. There should be three to three caps. Very good if Consider the mirror to be still, sir, this too should go on. is stopped as if the object is from four If it is going then this is also from four will go This is also clear sir, now what about the mirror? I said, brother, look at this one. Velocity will not make any impact right and if I move the mirror at 2 meters per second If I bring it closer, then give it in this direction will run at a faster speed 4 Yes or No Many children were giving the correct answer Many children were giving wrong answers so Velocity of object with respect to ground if If you talk, this will come -7 a cap 4 J-CAP Dil Banana Jin Jin Ka Yehi Aaye Aaye Tha -7 aa cap + 4 h cap very very If you bring the good glass here, the image will also appear on it. Some children will go in that direction No brother, take the mirror away If you go, the image will go away. Move the mirror closer. If you come, the image will come closer. Very good. Now the question. How can velocity of Image with respect to the object, tell me what to do friend ask about relative velocity If it is velocity of image with respect to ground minus velocity of object We have to do it with respect to the ground. So the image with respect to ground is -7 aa cap + 4j cap minus velocity of Object is 3 aa cap + 4j cap ye aa gaya Okay, so this will come to us -10 ah cap. Your answer will be Clear yes and no with anyone relative Velocity now with Mirror if you ask I will put straight talk straight talk with the mirror Sir three and four please explain brother finished be over a standard triangle which is 5 3 and 4 of 5 and 3 are 53° and 5 You know that the distance between 4 and 5 is 37°. Tax Take Clear Yes or No Yes Velocity of Image A The image will come here, okay, velocity of Image with respect to If the ground is fine then it will come -7 aa cap + 4j Cap, okay, this will also come here, this minus It will be done oh so - 10 aa cap and not this So it will be cut with us, so it will be with us. will come yes Clear Clear Yes or No Right across Children Where is our Pass so it's going from three so from three Here it is going from four so from four here If so, there will be no impact on us. And if this is coming from two then it becomes 4. -7 Aa caps + 4 J caps that's it okay and With respect to object to 3 aa cap + 4j cap will come to us clear yes yes Sir, won't you add these? Oh, this is it. Your 7 Aa cap is making you negative. I am clear yes yes ok so you have any If the angle remains angled then you are here now I'll look at the questions, okay, next question. Number of mirrors and number of images questions Let's see how many images we will have. JE Mains is now asking questions on this also. Okay, so many kids don't know this. If suppose there is a criss cross in it There is a method, it is a lady method, we don't care about that. have to go okay if suppose I have two There are mirrors m1 and m2 and between them is the angle of Theta, all the children, please definitely note this You can download three-four in the recent year itself. I'll look at the question, it's ok Now, wherever you are, if you are in the middle of this How many images are there if we keep the object The question above this will be made, okay. Number of images between two mirrors in this The first step is son, calculate 360 ​​/ theta okay you 360 / theta calculate out This will clear very good many children I know the matter, those who don't know it are forced Don't doubt it sir, it will come in fractions. So what will this be then by the criss cross method That is a method to question it. won't meet okay so 360 ba theta you Now these two options will be calculated for you. will give if it comes even okay then you What to do Number of images directly speaking The number of images that will be 360 ​​by -1 Simple thing, clear, very good and if this Your odd has come, son, so there are two cases in this. We have objects that symmetrically placed means angle bisector and if your object is symmetry not on the angle bisector The spelling may be wrong, don't worry. If that's not the case, okay, then here's your The images come in 360° theta -1 and here Images come in 360 ba theta clear hai kya All children please note this down. Let me take a value as an example I will let you understand it better Clearly, this is a useful thing, sir, where did this come from? Now is not the time brother, Criss Cross There is a method through which we extract it. However, it needs to be taught in batches also. No, you should use formula. Sir, what do you want to say as an example? I am saying this as an example So let's say I have two mirrors. degrees okay one mirror is this and one Mirror These m1 and m2 I have placed an object here I have placed an object somewhere I have placed it somewhere here. Find the number of Images Standard Question Number of Images how many do we have If there is any question of number of images then When it comes, you will see the angle between them. That's 90 degrees, son, so you'll do it first. 360 or 90, so this is 4 and this is yours. If it is even then the number of images is even If you talk If we do it then it will be equal to 3. Baat Clear Yes and No Three Number of Images There will be more discussion on this, JE There is a question on mains also. Very good if man All the children, tell me if you agree. So, I have given you a question that Mirror it was My son had a mirror and this was m2 okay the angle between them is 120 degrees Okay, my object is lying here somewhere. ok then tell me the number of images of this for how much What will be the number of images for this? will be clear Yes, so the first step is pass, you would say Sir 360 by theta Sir theta has to be calculated This is 120 degrees son, then you will say sir this is 360 ba 120 aayega dis and this has come sir In odd, I have to check that Whether the object is symmetrical or not, now many Children will say Sir Simtik means you angle bisector This is the angle we have bisector if the object is here If it is not different then it is different then I But I can say number of The images are not symmetrical in this case. If it is lying then in this case It will happen in this case, is it clear? Yes. If your object was here Son, if your object was here in this Case in point: your number of images If it were 360 ​​ba theta -1 then you are here If you had paid -1 then your answer would have been 3 - 1 2 Is it clear that all children once had a heart If you make it yes or no, you should keep this thing in mind. that number of images what do we have I know you have the formulas inside you. Doubt will come sir vert if fraction ho jaye vat If something else comes along for some kids There will be doubts about the negative too, please don't Entertain two kinds of doubts in your mind I am also fine, I did not ask you those things. We will go and see how to take the selection. Pay attention now, it's okay, for knowledge, full 2 years were okay in which by the criss cross method It is checked that the total angle we have There are a lot of things over 180 but Now you have to maximize your marks. It is clear that I don't want to become a scientist now. Here comes the field of you, okay now it comes to the point Field of you listen carefully one mirror many A child was also saying this here just now Sir, if the mirror is somewhere else then there will be no image. Now we will have the last scientists I come to the floor batch to do my PhD thesis I'm fine, so let's talk about them too. So let's say I have a mirror here. And what image will be created if you stand somewhere here? All the children tell me that object The mirror is here, what image will be formed? First of all tell me whether it is yes or no brother He is a scientist but still does shallow things. If you study then you will cover all the physics. I will cover all the physics in one go. But the image It will be made, hey, look, they are the ones who have no say. It seems like he is not in front of the mirror. You won't see it, but it will be there You must have tried this many times you have to chastise someone okay It is your action that there is no difference between man and woman. Both come, the mirror is fixed here somewhere Now if you look directly then it will be a problem. We have past training in the company POS H so it will be applied so what will you do Look in the mirror Look in the mirror After seeing him, yes, stare at him. Have you ever ridden a scooter? It must have happened if someone is after you. By the way, you don't even know the physics in the mirror. I know it but yes when it comes to work then Everything seems to be yours, Sara If the child has experimental data By adjusting the mirror comfortably, you can see the thing that I want to see it, if you watch it with great interest then if that If I was not in front of the mirror, the image would not have been formed. I wanted it, I had a son, but at that time It doesn't come to mind whether we are in class or not. I gave such a stinky answer to Sir that If the object is not in front of the mirror The image did not get created, I said okay then If it makes a little difference then whatever light If it has fallen here, it will go away like this, whoever The angle of incidence of the light ray falling here If it is too much then it will go away like this if you You will extend both, right? Son, it's okay if you do both of these If you extend it, you will get the image You will get the image but this you You can't see because whoever is here This is your reflected rage. RRS ok this is your reflected Whatever race the person expressed here They must be able to see it because this In the region we say field of view is a A region from which you can see things You will be able to see the image that is called field of View is the first important thing Points are now important in happiness Don't miss all the points, the first important one Point what ever may be the Size What Ever May B. The size and location of Mirror of Mirror Image Is Always Formed Image is always Your image is always formed, uncle. Attention Keep it, you just need to have the intent to watch it. You just need to have the intent to see it, right? And a little hard work and a little common sense Also, okay, now the mirror is in front of you, it's here. Now if you look up you will see a little If you see it, you will see it in the mirror. There must be intent and a little common sense There should be a mirror wherever the image is always there Banega Aap Kya Karye Dr N Extended Mirror Dr N Extended Mirror: You make a large mirror. Okay, you make a big mirror. Take this like this is your extended mirror for still whatever your object distance Your image distance will also be the same. Diagram wise it is not coming but sentiment is there Understand yes okay dr an extended mirror Object Distance Equal Two Image Distance Still will be clear Yes, the position and size of the mirror How does that impact field of view? will set Understanding Size of Mirror Will Decide Will decide okay will decide the portion of Image Visible The portion of Image Visible, listen carefully brother, it is very simple. The story is fine if you have a small house If there is a window, the universe is outside. The whole world is outside, even if it's small You have a window, so when you look out of it So you only see a small region. If there is a big window then you will get more The reason will be visible, it is a simple matter that the mirror He will always create an image, first of all. You need this object distance equal to image The distance is the same here as it is here This is called Image World Image Key The world is fine and this is your object The world will always make you smaller if your mirror is smaller If it is small then it will show a big region. If there is a mirror then a large region will be visible, yes Or don't say yes or no to everyone on this right now. I know, even if I don't ask the question, child He starts talking right away Isn't it a rut, look, he is coming, Batu mirror too See Self is OK Yes, depending on how it is used. I also have a question, very good, the train has arrived, okay. What is the question, just as an example Understand it okay is the minimum size of the mirror to form an image Tell at least all the children who know Minimum size of What is a mirror to form a complete image? have to form complete image if mere ko If you want to create a complete image, then the minimum size of The Mirror How Much Should Yours Be My Punter All children first tell Yes A Batu I knew before that A Batu You must know how to write, okay the answer is point The size is fine, it doesn't get half off. what hey brother o rattu Parrots, okay, if I take a parrot, then that too I will tell you this parrot, okay point There is a size, sir, I had read h Batu. Think about what you read. Look, whatever you read, you just memorized it and sat down. He is talking all day long, O Batu. Yes son, if you stand in front of an elephant If I bring a small mirror in front of you Okay, so he will complete the image. Even a small mirror will create the image of an elephant Isn't it a big object, so it is I will make it big but I will show you a little. I will just give it to you, okay, I will show you a little. Only this portion must be visible, yes and a quarter absolutely the human minimum in English Size of mirror to form complete one size What should be the minimum size of a mirror? It should make the entire image point size Mirror also creates complete image, not visible I will give you yes for what you have memorized. No son, just read it, okay, because If many children get confused about the question then h Batu Example to minimum will come after marking Size is ok Minimum size off Mirror to See Your Complete Self for to C Complete Self: To see yourself, at least How small a mirror do you need, okay, at least. It's a matter of how small a mirror you need. you have Spit out your anger, spit out brother you snake Spew out your venom, many children have said so. Incomplete Answer h / 2 Remember if the value Take a man of 1 meter height. Isn't it common sense, what did I say? If you need common sense to read optics All of you said that Sir, at least half I need the meter mirror, so I said, okay, here. I will keep it 5 meters, what will it be able to see now? tell No no, tell me, tell me De, you are standing here, whatever your height was. You said Sir, the mirror is of Batu length. I said okay brother, take me to the fifth one. If you put it on the floor, what do you see? Will you be able to tell me, see? will take Yes, then you will have to remember the conditions as well. Brother, you can see this anywhere. Yes, oh my god, brother, please look after some children. You see Mahabharata, we knew this only Ashwat Thama remained alive in Mahabharata Later we did not know that Dhritarashtra's Sanjay, who was in front and was far-sighted, saw everything. They were taking, they got the power, that is you. I am alive, O Lord, please bless me. We have come a long way in PW. what are you talking about Yes brother, Sanjay ji is alive, Mahabharata It's okay, everyone can see the mirror somewhere. Keep it all in view Yes, come on brother, remember this question. I have to keep it, but you guys remembered it, The height of the glass from the ground is also There is a condition of the eye, the level of the eyes from the ground his Half okay, let's come sir, how will we do this? You are not doing anything to worry about him. Why are you taking it, you are just memorizing it. Come on parrot sir, I will tell you how to memorize this. Now okay, first I considered the entire mirror. Take it, let's say you're here, okay, neck It's a bit long but it's okay No problem, okay brother, watch it completely. If there was a mirror, I would have said, brother, image So this is always if it's at x distance. Its image is exactly equal to that of a plane mirror It will create exactly the same image. x distance But at the same x distance Clear yes if its height son h is attention If you look at it from the outside, its height will also be h. You know the size of the object and the image. The size is equal, we need to complete this person. If I want to see him, I'm going to assume Its eyes are right on the skull, so at least You would need a mirror of at least this length. Dude, look carefully, at least this much length So we need a minimum mirror. Size I created an image world a Object Distance This is your HD Joe us here Do you want it yes or no, now many children will sing sir How does its eye fit exactly on the skull? Leo, I agree that it's okay that there are so many If you are assuming things in maths then I accept one thing here, very good, okay So this triangle is a b c d And e this little triangle abc2 triangle The value of AD is 2x your value of AD. Equal add ba e to h d e h Batu it happens clear and you have to remember this thing that this which is glass No, it's okay, this mirror should be plaid if you talk about eye level this e Your eye level is right here. Eyes are fine So you remember the level, mirror should be Place at Distance at Distance from Batu Whatever your level of ground eyes I Write here what is in the h batu. I give it to you okay h of aa eyes whatever The level is divided by two from the ground, your being You should also want to extract this from the similarity So you can extract what is the concept that The minimum size of the glass is h baht And the ground from where you get the ground You have to keep this path, this is also yours. Is it clear, yes or no, tell me brother. yes or no Yes, I have another question on this. But I have another question for all of you. Tell all the kids that the honor Take a person It is standing 5 meters away from here. Okay, this was his entire room, that's 12. meter like this we have okay minimum Size of the mirror all the children to me State the minimum size of the Mirror Minimum Size of Mirror to Sea Complete Back Wall to Sea Complete Back Wall How much minimum is needed on this wall to see having a shaped mirror All the children should do it now, do it, do it Do it son, bath happens when at the center It happens, don't memorize it, it's okay, don't memorize it, friend. ask the question ok is h3 Hey brother, the parrot was left to memorize Why was your work on earth responsible? Have taken it here But look, if you believed the whole mirror, you would say that The image will be complete whether the mirror is small or big. Yes, the image is complete The vision of this person will be fulfilled. If I talk in the mirror, its field off view how will you set it like this sir If a person can see this much then the question arises This should be the field of You have to, this should be the field of you to This mirror is of no use to me and This mirror is also of no use at least. I definitely need that much glass. It will be able to see the back wall only when it is working So the question is, you take this A B CD And look at your little triangle. is a similar to triangle which one is yours A So all the sides will be in proportion and the height too. If it remains in proportion, then if I talk here I have perpendicular height and this is This is what happened to my attar punter, you can say The smaller ones are in a triangle divided by a by b s e equal to a divided Bye finished so how much is it son pa B S B S We need h let's say A G so this How much will it be, son? 12 This is your object distance 12 12 p 5 17 Divided Bye we have Okay oh, I did not give this to you, dear sir. Let's take it, okay, we have it. For us Clearly, what you want is 5h ba 1 We should have a mirror of this height Chahiye Clear Jo H Bath Rattu Tote Ke As I was saying earlier, son, that is a different case. Brother, someone please give me some water Hey, everyone is getting free money, brother. Hey, it's holiday, light Brother, you left everything and ran away, brother, the last one There is no one in the class, wait friend, I am thirsty. doing It is cold Friend, everyone disappears here at 6 o'clock. They are wasting money on Just no one or lukewarm water is fine Listening from outside as soon as the chanting came on Everyone came in line, yes, okay. So son, what have I got for you here? said some child h bath when here in center of When D is on it then H bath happens, don't memorize it. Okay, don't cram, now all of you are in class 2. People are the kids who bring it to 105, right, in Davi. you got The code is fine, even without studying the child is a topper And then he said that we should remove IET from here. Can you tell me right now that I have at least 500 rank? The children will eat Have you created so much air in your house that Papa also felt, oh my god Father is our child, this without reading 105% Covid has brought marks in class 10th They put you here, brother. I feel like the country needs you If your okay then You all have come, now we know that brother Sir, there is no Covid, there are many other topics. The Spherical Mirrors class taught at Dwi It was removed in 12th because The government felt that if my friend studied in Davi then They have kept the child, what do they know, the child memorizes remained For them, brother, it ends in 10th. Ours is gone, right? So, spherical mirrors are yours. There are mirrors that we have from the surface are removed okay like let's say your There is a sphere, okay, explain it to the government. It will have to be brother Our child is very dangerous, okay once He studies only till 10th, that means 10th, not after that Achieve many things in life by looking and turning Where to look back, where to look Don't go, the child is moving ahead now. The problem is that whatever is related to the topic of Baavi, I am not able to understand because 10th is tough. The topics became tough because we studied There were none, so optics went out of hand. No one, son, when you are from a spherical surface When some glass is made, we call it Remember these spherical mirrors if you I remember something like this, okay? Some masters tried your career To make sure that the child will study and go ahead will make the name shine If the child does it then enjoy watching the reel Coming to the topic of Bavi where tenth comes He says deleted. And whenever my topic comes up, I say it there Is Repeat, the child gets stuck in that loop. Went Yes So when you turn a mirror into a spherical surface We make them from, we call them our There were two types of spherical mirrors. Remember, you used to have a concave mirror. Children were asked to memorize A cave-like mirror with a cave inside. This is called concave mirror and whose reflecting The surface on the outside is the bulge out surface this is called convex Mirror okay the sphere you used to make it I have found out that this is its centre. I called C and the center of this mirror would be This is called p pole, isn't it? The center is son, this is called sea and what it Center is this is called poll remember if We also have the radius of the sphere, r. This has come in the JEE Mains question. See the question r/2, I thought it was from 2022 I asked the question whether to put it or not. Leave it, children should also gain confidence. No, when we apply p back then the sphere Radius if your R OK If the radius of the sphere is R, then Make Maggi too, I have brought it so hot. Not much brother, just a little bit Hot brother, show me after drinking, I will accept the money. I will give up Firstly, there is no hot water in our company. If you tell me brother, our lecture is of 100 degrees. Sitting outside, observe the thermal properties off met calorimetry so these q e a in a It can be brought only after applying latent heat of vaporization. People forget to drink water I am asking for some salt to make Maggi. OK He opened it and brought it saying that it is hot sir, drink it Show me brother and our one month's salary Take it away like water flowing from here will go away no problem thanks Brother Yes Let us come brother, if this is your question then In this, their focus is the focal length that is equal to r but half of the radius okay Important points to keep in mind are the questions He has come, this is important, this is fine. Secondly, independent Brother, please tell me this also about the medium, Independent Off medium, put it in water and kerosene Put it in Maggi, put it in Focus your beans It will remain the same, okay, okay, okay Look carefully at the lights we have. Also, light comes to us parallel to Principal axis we have all the all rage Whom will we consider All Para Egal Race sir parallel race kya ho hai jo close to We have principal access, okay? We call those who are far away Marginal Reasons Paragraph Agele in our Syllabus It is a matter of height, that is, your height. that will be very small very close Small angle approximation will remain our Passes become valid okay so after The point from which the reflection reaches us It does this, we call it focus. But it happens when the light comes to us here So this is about a point, this is normal. Son, if she goes to us like this then This is your point, this is your focus. Oh normal me, look where are you passing from? If it is normal then it will pass from the centre, this is fine was your Normal is fine so the light is on our The point about which the passes diverge This is your focus, this is your focus on Aa Batu Hai hum beta Rick Rohit I love you Ishika likh okay but it's in the wrong place you are writing well Hey, do it, go ahead, Tinder, Pindar, okay There is no class on your undergarment. The class is going on at t, you can call it t Leave it, don't make it a wonder, it's okay to study. Tax So the first thing is always turn on the light It converges, it is called a converter The mirror will always be converging to the lens. Convex lens detaches from case and concave lens refractive index Okay, this is always making the light diverge. is this called diverging Mirror, what do we call this, son? Diverging Mirror Clear Yes or No Yes Very Good Very Good Now all the children here are Memorizing diagrams Do you miss this brightness? I'll reduce it a little bit, okay, all the kids. I'll give you a thumbs up, okay, one thumbs up up will you do this are you missing this thing If you write yes or no, it will appear as thumbs up. So don't write thumbs like that, do yes and no. If you give it in chat, it will catch it automatically. Whenever your object is sir these are useful I will show you the question through your eyes. Tears will start flowing because he asked this for us also. Yes, some children would have shown all this making fun of things Yes, I have given him his homework, now I What should I do if the light ray object has been Reflected Toward Observer From What kind of image is formed in a standard flat mirror? It's real, virtual, all this is fine, this is our The focal length is the object distance so If so, how would the image have been made, this one is Number of images Image is inverted is real Depending on the position of the magnetic object, you The same questions are asked on this also which When a 10th class child sees It comes to him that I RTN I will become son, only those questions do not come and There are also questions that you will need to consider carefully. Yes, you will note this down and remember when object I'm telling you when your If the object is at infinity then your image will be Real inverted and highly will be made on focus Dim if your object is beyond the center It happens this is the same illusion okay so 10th Yes to the children of the class class at this place brings us to our center's beyond When it is close, the image is in your focus and its It is formed in the middle, okay, we have a real will remain inverted will remain diminished At the center of curvature when we have If there is an object of the same size, it is there The image will be real and inverted when If your object is between c and f Beyond Sea will become magnified and real And inverted will be okay hashtag that hashtag saying exclamation mark Make notes and save them for later use by whoever It's a problem, it doesn't bother me You know, this is the easiest part, everyone I know okay then if the focus If the object is at infinity then our image is at infinity It will move closer and will become highly magnified. Real and inverted if this is the case for all of you people have to keep in mind that if We have that between the object p and f So this is the only case in which this Creates a virtual image Okay, we would have a magnified image. It is very good magnified, we have the image okay and we have virtual and erect There is an image and you remember it in all cases What to keep in all these cases In cases it is creating real images and There is only one case in which this Creates a virtual image for us creates a virtual image here with us is clear Now that this is about Devi, now I will tell you about it. I will ask you to make a graph of Y vs Y for 12th. talk Let's all the kids make this Y vs Y graph. will make it okay Now this 10th class child is doing Hesitation is not in you. It should be done quickly and rough of V vs Y For a concave mirror we have What will happen, all the children will make you JE We will find these types of questions in Mains. There is more to it than this, More graphical analysis is very important Okay, what are these points? All the children, please look carefully, this is your Is f0 it's yours 2f 0 ok it's yours mine f0 and this is yours ee 2f 0 this is yours 0 f okay in the same way 0 f end 0f like that How will the graph be made? See when concave mirrors are right for you here now No, many children will say repeat before this Understand when the value of Y is for you If the value of v is minus infinity My is f and the value of y is when - 2f If so, the value of v is -2f. If the value of y is -f then the value of v is The value is minus infinity for all children. Make up your mind about this Yes, all the children, yes, I did not understand. All children should look at this diagram. Sir, where is this minus sign coming from? minus the value of u with convention When it is infinity then the value of v for you is - f is very good love you then how will the graph come All the children please plot its graph. will do it okay all the kids see its graph We will plot this graph of v versus u. The value of is minus infinity then the value of v - f graph will come from here somewhere and This is a point where mine is 2f mine So the graph goes somewhere like this and Then it becomes like this This will be your graph and when it is for you Understanding the value of Y for you carefully minus a is less than negative means less then i Key Values ​​Come to Us for You If it is positive then you should remember this graph. is the value of y minus a and between So this graph starts from plus infinity. happens and it goes like this this is the graph Whose heart did this match win? Make a match between whom, make a heart This is very important, this is the second class. 12th class is for us if you are a concave I am making a mirror for my son, understand meditation. This is your focus. If you lose focus, If I put some object here, you will remember it. This will become your virtual In this way, your attention should be considered negative. your minus f is near okay so v your going towards positive infinity How did your Sir Graph get here then I will ask I'm going to be looking for the value of y around minus f So the value of v is plus infinity and like As soon as you bring this object closer image comes to this so for us this The graph goes and touches here, love you son, this It is very important, okay, this is it Zara Convex Okay, if you look at this convex mirror If you make a v versus y graph then I will think That yes brother, I have used my brain to enter our Painter has v vs y graph for a Convex Mirror Let's See Who Would Have Thought Yes, it will be available in the option there. But if you keep making it, the method of making it will also change. The approach also has to be understood whether you memorize it or not. Rote learning is fine but you should know at least the approach. It should be so, sir, why are you making these four lines? Yes, we need a line of f and 2f. Let's see this. Let's go to 10th class, let's go to 12th class. When in a convex mirror object when your object is minus infinity So its image is formed at plus f remember Make this ray diagram in class 10th you have a convex mirror sir whatever Your light will come on the object if your If it is at minus infinity then sir this light is like this The image will go into focus will be Yes Yes yes or no, as long as you Objectives tend to zero, which is meditation. Understanding how your object will approach it So for us the image would also come close to this So what should your graph be? View all children minus the value of y infinity value of v plus f so p f this and minus infinity is this so the graph here and the value of y is the value of row v If we have tends to 0 then this By doing the graph somewhere like this we have So this is your convex mirror Graph yes or no will now come repeat repeat If you listen carefully, you will automatically learn to repeat it. Please do it Brother, this graph is very important. The v versus y graph of a convex mirror is and we have v of concave mirror Versus y graph is like this hi very good love you son okay so this is yours things we have now after this All the children listen carefully and I would call this the exclamation mark. Instead of writing notes, it is better to do it in a copy. Write it down because it's something useful. If you have a concave or convex mirror Mirror Any if yours is a spherical mirror ok if object e listen carefully if the object is Plaid is fine this Plaid near to a Mirror near to mirror so image judge formed Always your image will be the form image is Form Clearly, we will always have an image. There is a relation between us. Object Distance Image Distance and Focal Its length if the focal length is f which is given by r bat okay so 1 up f e 1 up v pv You used to call this relationship your son. Remember the mirror formula, what do you call it? Hey son, your mirror Formula positive in many children Negative would have been a big problem Isn't it true that many children are positive in this? Negative is a big problem, Sir Mirror. Was there a plus in the formula or a lens formula I was plus sir its magnification positive had its magnification been negative, it would have been So what do you have to remember when starting out? So you always do it with positivity. Mirror formula comes first in class 2 I came positive, I can remember this much later You always become negative, don't you? So the lens formula comes after your I have to memorize the negatives in the syllabus like this fine parrot If it is clear then whoever comes first will be positive. Now you have to remember this here, okay. We have two types of magnification Who will tell me brother what kind of Magnification is Yes, we have two types of magnification. There is a magnification called your Lateral magnification carefully Hearing is a magnification lateral This is denoted by M lateral and this I nothing but we have the height of image by Height of Object clear very good transverse saying Whether it could be called transverse, it would have been the other Longitude magnification okay this is called Longitude Magnification questions will be asked by everyone, son. Longitude will question everything Magnification which we call M longitude denotes the thickness of Image by thickness of object is clear Sir, what is the thickness? Hey uncle, please pay attention. If you look into any mirror If you are placing the object like this then this I called the height of the object and if you If the object is kept long principal then Thickness of object means I will write here okay length along principle of axle length along P This is what you call thickness. off this is what you call thickness and whatever Yours Length Perpendicular to Principal Axis This is what you call height, son. what do you say height is clear what yes or no Yes, don't write the notes now, let me write them first. Now, everything is carefully Listen when the plus comes here It appears negative under magnification. You have to remember the mirror formula. If you read it first, then with a lot of positivity Read more positivity over If it can be converted into confidence To remember the magnification here - v ba Y comes here if you have plus here Minus will come here if you have plus My of v s / u s you saw It will be clear now, still wait brother not in the notes right now okay this one There is a formula, there is a condition on it now. You are better at writing questions From this you will understand that its condition is small thickness that if your thickness is too small so that If you are having trouble calculating You use this, now we will take it. If you also ask the above questions then you will get better results. This will make you understand that you have to listen patiently. If you place any object, an image will be formed. So here we have the object of both of them Distance Image Distance and Focal Length There is a relation which is called mirror What is formula u sir, this is speed This object distance is Where is it from? Measure from the pole itself Let's measure okay v what happens image Distance from p Okay, what is F? This is the focal length. Where to measure from Fifth note of musical scale clear Yes, we Anmol Sharma son suddenly understood It won't come in the last batch, see the same thing. What happens in the batch Stress-free child now studies for 10 days There is an exam later, your concentration is here. Even if you stay, you will learn your The problem is that you are going to appear for the exam after 10 days. Trying to read in last mat under stress That's why you need more things like this I wonder what this is, this is a second class thing. So, suppose your tomorrow is after 10 days. This is not an exam, you need to listen politely once. I will try to ask a few questions pen This thing will work, now here is your signature convention remains okay now this sign convention through out we will follow sign Convention Listening Attentively Okay, all these things are from the second grade. What is the Convention on Direction of Incidents? Ray is always there for you Positive: The direction in which the light is coming If it is on the mirror, you will take it positively. Watching children Just look at the direction in which the light is coming. You will take that direction positively. Distances are measured from poles All Distance R Where are all the distances measured from the pole? From the size of any mirror to the from pole Okay, secondly, we have directions. Distance Measured Distance measured measured in direction of in Direction of Incident Ray Incident Ray If you measure anything in direction You are positive about him The measurement is fine, distance measured in opposite Direction of Incident Re you are negative towards him The measurement is clear son, please be very careful. I can see the comments clearly, so Please focus on this thing first. But if you have any glass If something is measured above the principal axis If you are measuring something below the positive measurement If there is a negative measurement, clear yes or no All the children should say yes and no. bro yes or No Clear everything about your incident. Measure in direction whatever you are measuring He measured the incident with a pole. Measuring positive and opposite in direction If the measurement in the direction is negative then it will be negative. Positive down measurement then negative clear one Let's do a question from class 2 then you understand things will come fine Let's ask a tenth class question. So that children can understand things better. okay let's say I have a we have concave mirror okay its Radius e 20 cm I have given it here So it is obvious that we have one focus. I have a nearby center of curvature which The object is lying somewhere like this okay this is my Object is fine off length 5 St. Okay, this is my object along the The principal axis is 5 cm. Near object is find the length of the image Come on brother, find the length of the image with this question. I will solve this question easily, you will be satisfied You will be able to understand everything clearly have to do Son, you have to do it politely here. Correct now what is a o look a this object Yes sir, if I had kept it like this, we would have If you are keeping your height like this then if you are thickness then Somewhere the thickness of the object will give you If 5 cm is given then what is the length of the image now? will be Who all the kids are understanding this? Whichever center, thumbs up, whichever center of If it is on curvature then its image will be at the centre. Sir, its image will definitely be created somewhere like this going to be Think and tell me yes or no sir, whatever the object is If its image is at the center then it is at the center It is created and as your object The image moves into focus, here beyond the sea. It goes like this, yes or Na very good The size of both will not be the same as u There will be a change v If there is a change then I will not be able to Somewhere to see every end Suppose I have a Rod took a and b then the image of a will be a d b Where will the image be created if I come to know? If I go, I can find the length of this image. simple If it is clear yes or no, then please understand If I talk about the solution, the image of An image of a to woh to at sea hi He will become C but all the children will become B. Let us find the object distance of B. Let's talk about the object distance. With sign conventions, let's see who Can you think of anything? has all the children for B object Distance your kitna hoga sign convention Of Look brother, the light will go on the mirror. I would consider this a positive direction. All things from you pole Measure clear very good so you will get this from the pole You will have to come for B, so when you come here So you've gone in the opposite direction, so you First of all, some children have negative measurements. Donkeys are saying positive, negative measurement Because the direction of incident is Ray himself Anything in this direction is positive. If measured, this direction is positive. If I measure it, it is negative, so I measure it here. Its focal length will be 10%. Centimeters, how much will this distance be for you? This is 15 centimeters, so you would say 15. centimeter Very good, just see if I focus it. If I talk, tell all the children its focus How much will you take, positive or negative, let's see All the children, tell me your focal length. What will you take with positive or negative thinking? Tell me Tell me, positive or negative sir, focus? If I am here, I can measure whatever I want. If I measure it from here, sir, it will be measured here. So sir, this is in the negative direction. Very good sir focus will be -10 I said be So gaya aap to 1 up f e e 1 up v p 1 up u Subtract - 1/10 = 1 bawi we have -1 Ba 15 So if you look from here then 1 bavi aa Your son will go 1/1 - 1/10 If you do LCM like this, your son will get 30. 2 - 3 Okay, then you will get the value of v - 30 centimeters Very Good That Means Understanding Your Image No son, analyze this. Do whatever your image is here, son. Analyze this, this is your f, this is Whatever image you have created, it is something like this Bani A has come here and your bead This one's length is coming to 30 centimeters. In the negative direction, then this direction In This length of yours is 20 centimeters, right? If so, the length of the image should be the answer. Jin Jin's heart has come to make length of The image that you That will be equal to 10 centimeters. This was the answer to Dil Bana give Finish understanding yavi sign convention the whole thing told Clearly, some children say that Sir, our what is this formula for what is this formula It is in this question, okay, now I will tell you. I am in the same question in the previous Question Previous Question If I do Look very carefully, son. It's important, it's okay if my The previous question should be like this Let's say this is what I gave you Radius T 20 centimeters I placed a small object like this is 2 millimeters at a distance of 15 Sutter okay find the thickness of the image now The question is Find thickness of image. Now the question is Come on brother, let's see who can think what. All the children, please take care of this thing. But now my question is find thickness of the Many children will say Sir as soon as they see the question. This is the past perfect question, no son, in this Now the difference is in this your calculations Will bring tears to your eyes, some children will say Sir A and B I will take it like you did last time. I will create a separate image of A and a separate image of B. I will create it and find the thickness of the image Son, if you want to do it, you can do it Bano Miyal The calculations will have to be done, they are very dirty. will go because its object distance is thou What will he take? He will take 15 centimeters from the other. Death is coming in 2 millimeters calculation what will you do now So when your thickness is very small, son? For small thickness, carefully Listening when your thickness is too small to You seem to have a problem with the calculations. If it comes, you will use longitude magnification Use the formula this is the thickness of the image By the thickness of the object that is - v sba Y sk very good so iss liye direction of This will be the incident, son, if it is positive The value of Y for you My focus will come here only, the value of A will come My 10 so you 1 your a ive Anvi Navi Psav Try this and this So I kept it there and wrote minus 15. It has happened that mine and mine so the value of your I will use the same to make the calculations easier. I have said this for 30 centimeters Yes, now when there is thickness then you can directly say Could be the thickness of the image I wanted The thickness of the object was 2 millimeters, son. minus off square so 30 not 30 you would say upon ya square 15 in 15 you here If you say this is your tip, this is your tip. Gaya beta four to thickness of image mine 8 MM will come This does not mean that the thickness is less than zero. What is the minus inverted image telling? Meaning to say, if A and B were there then the image was yours something like It will be made of 8 millimeters, okay so this is yours here It will be yours, whatever we have or yours B will be here, yours will be here, understand A to B If you look at the direction, it's from here. If B is here then it is in the opposite direction Oriented will be clear yes or Neither yes nor no, so what is -8AA telling you? Hey son, if you hold the pen like this, the image will be like this The reverse image will be formed here. It must have been clear, yes and No Clear, clear, very good, now its the last thing You have to pay more attention, okay, last thing. And then we have to pay attention and ask more questions. Okay Velocity Magnification carefully listen okay And these same formulas will continue later as well. Velocity If you ask magnification questions now Son, you will question everything politely. If we do it from here, it takes seven to eight hours, so a little You will have to show patience, Velocity Magnification is fine for those who need a break. You can take it, no problem, okay What is velocity magnitude if the value Sir, do I have any mirror? Are you talking about a concave mirror or a concave mirror? convex both Mirrors Meditation listening for both Mirrors, listen carefully son, very It is important that you have to ask questions about it many times. My first question to you is if If I move the object, will the image Will it move, yes or no, first this Tell me yes or no, first of all, if your question is I'm moving the object, whatever it is. If the mirror is convex or concave What if I'm moving the object? Will the image move? Yes or No. Yes Sir, Obviously. The thing is sir 1 up f = 1 up v + 1 up u If the object distance varies, the image Distance will also vary right up to the object You can also move it like this, case one is this also You can also move the object like this If this is okay, I'll tell him This is velocity of object perpendicular to principal axis this is velocity of object parallel to principal Axis, this much hint is enough for an intelligent child. Even if it happens at an angle, give it to me. We have velocities on the axis. I may have to resolve it, okay, resolve it. You may have to, so remember that If the object moves, the image will also move. If the move If it does okay then the image will also move, you All the people have Said it will move, don't go for derivation have to understand the concept ok object move If it does, the image will also move if the velocity Off Image perpendicular to principal axis If you want to remove it, you will use M Lateral Into velocity of object perpendicular to Principal Axis pay attention listen to my words completely concentration velocity of Image parallel to principal axis if If I want to remove it, I will use m longitude into velocity of Object parallel to principal axis first All the children should note this down. Look, some children are not able to understand the basics. If yes, then son, I will prove it to you here. I'm not sure if it's basic or not. Okay, I'm just here to teach you. I am here to read, read, don't read, suit Suits can come off Are Clear Sir, now let's talk Sir M Lateral and M How do we find the longitude, hey crazy M of the lateral Your formula was minus by and em The formula of longitude and your Object in Minus Buy Questions Distance would be given that I know where it is, I know, please take it out. So if both your magnifications come We will write velocity as will take Clearly, this is the whole story in this lens. It will also work, now we will learn it from the question Okay all the kids just give it a try If it has happened then how will you go back to the pole brother? Which pole is this There must be someone, come on brother, let's see all his children We will talk, okay, one light e Reflected from a plane mirror with 30 degree angle of reflection the angle of deviation of the light i ok sir angle of You did not teach me any dish, brother. You will learn from the questions whenever you have any Listen carefully to the mirror. On any mirror. when the light comes down Okay, so this is your angle of incidence. So your light went out here, this is also here. Yes, where did the light go? This is the Initial Direction Initial Direction of Come and the light bends from here to here somewhere ho gayi hai this is your reflected ray to We call this the deviation angle prism. If I also take it out, you can see it from here Then this deviation angle i + i + delta should Be equal to Pa so this is Pa or else 180 - 2i you can say of a plane mirror The deviation angle is clear, so they Given that it has a 30° angle of reflection then angle of incidence is equal to angle of If the reflection is 30°, then your answer here But it will come that is 180 my twa of 30 so 120° Your answer here will be option B. Write a or b write you here v b Your option here will be the answer Very Good My Ant Punt I'll see the leaderboard at the end. Finally, the leaderboard is of integer type. Okay, start common sense to vertical. Plain Mirrors A & B are Separated by 10 centimeter a point object o whatever here But the children of aim and effort will be this We talked about logic of this type, theory. I also did it because we had some time. Children who will be new, sir, you aim and try If you are not teaching as per your wish then you have not studied it as per your wish. I am staying because there is time constraint But I have been studying the same things and I'm talking about what's important Okay, two vertical plane mirrors are the best First question, okay first because that too is inti You will come to know about it by writing it in theory. Tell me how many images are made How many images are there, hey friend, here are some The homework answers must have been very clever. I have children, I try to hide them Some children will say, Sir. If you give homework, write down the answers. I said let's write something like this We will have a lot of toppers coming. Friend, wait a little, what do we have to do? You will have to mark the answer secretly. First of all, I wrote another type of answer, brother, not in all of them. There is something in I will hide the answer first, otherwise brother I have published more books after eating food than physicists. Even if they do another printed one But first hide the answer brother, it's okay now. Some answers are written in it, it is okay Come on brother, you must have come here 100% now. If you are not able to bring it then brother you are solid, you are fine If you couldn't even do this much, what could you do? No, it's okay, I've already seen it brother. In this the number of images becomes your infit Also keep in mind the question Number of images Your infit is formed, sir, why would it be like this? Hey brother, the more times the light comes on, the more If bar images are made then what have they done in it? It is said that there are two plane mirrors, you just See how it is, all the children, take care of one mirror this is a mirror your this is okay theta Put the value of zero and it will become 360 ​​degrees infit. You can do it anyway, this is your mirror. There was an object at a distance of 2 cm. and you have given 10 centimeters, then this is your This is at a distance of 8 centimeters from you. I have given a question, he has said a point Object O is placed at a distance 2 centimeter from mirror a the distance of the Second now finished in English all humans Children, see the distance of the second Nearest Image Behind Mirror A is a mirror behind which the second image is formed I have to tell its distance, okay from The mirror will be like this brother, look carefully infighting on this First of all, go to the mirror and see If the object is here then this will be the First Image by Mirror A First Image is Mirror A, then at what distance will it be 2 centimeter So he will say that you will make it and we will also make it. So we said, make it, then what nonsense are you talking about? So this mirror is 8 centimeters away from this object. If it is at a distance of 8 cm, then it is at a distance of 8 cm. Your image This is the first image by mirror We have a mirror that has formed its own image. These It's not just one, this is his too. If we create an image, just watch it. How far is this mirror from us? The distance will be ok All the kids nearby, just look at this one. He created his image. He created his image. Now will we have this object of yours? The distance will be 8, 2, 10, and 18, 18 centimeters. But he will say show me another one, show me another one of this. If you make it, it will make it its image. So the second image by mirror A will be 18 centimeter will come to 18 centimeters then this The father-in-law will say, hey, we have created his image. You will also make an image of this, so please do it here. Look carefully at the second image that will be formed. This is how you have to keep doing it, this is the Second Image Mirror I have created its image, now give it some distance. See how much we have 8 to 10 p u 12 centimeters so this is 12 centimeters And so on up to infinity and so on up to Infinity Clear, all the children, please look at this All right, all the kids, just look here. That he said this in the second image. How far was the left mirror from this mirror? 18 cm, this will be your answer 18 It's Yours Answer: Okay, today we are more technology I have told the children that yes, if it has come then 18 We have it right Zero's writing will remain, O man, it is coming now So we all speak very fast. Technology is used and it gets spoiled. cheating that kid When people see the leader, they get angry, ba tha ho Our entire technology gets leaked. what did you say in class brother move away Brother, take it Came Aa three questions correct Adi Shah got 13 You have taken three seconds to attempt the question. three that's right okay lots of kids Yes, okay, there will be a lot of children in total. We will see later, okay then Adisha Very good son, everything is going well for you. If the program is correct then 18 answers will be next Please give us all the children and let them see the answer. Okay, we'll give you a 45-second poll. Start an object is played at a Distance of oh friend, it may not happen that I minimize Yes, this would have been a problem Tha pole also took time to start But it doesn't take that much time Wait, we should complain now. wait wait Mardawa, all this technology has come to us Why do you fail in class, friend Dinkar? Sir, you must be watching, for sure I know We have to do all the work A 503 error has occurred Take Hi hey hey what's going on Son, wait a minute Go sir, there is some trouble in the poll. just look at one Bar good internet issue Is Yes, okay, okay, okay, keep watching, sir. Yes Okay, yes, technology is involved, okay, so let's go. Let's look at the question first, okay? Object Plate Distance 12 cm in Front of plane mirror You have a plane mirror what did you put son at 12 centimeters in front of An object is placed virtual and erect The image is formed by the more obvious thing If this is the object, then the image that you have It will be 12 centimeters is moved by 4 cm listen carefully Move this mirror 4 cm away from this position. It means it took me here towards the stationery. object distance by which the position of The Image Will Be Shifted All about where the image will shift Children, tell me this first, not now you If you are answering then there should be no problem in that. Brother, if you shift the mirror here, then the image will also shift here and if you Shifting has been done, the shift is of a centimeter. Remember, the image will run twice as fast, so this 8 centimeter According to the ground, these are 8 Centimeters Towards the Mirror Wrong 4 centimeters towards the mirror exactly this Four has moved, it has come so 4 centimeters Towards the mirror exactly 8 centimeters Away From The Mirror Wrong 8 Centimeters Towards the mirror for the wrong mirror then 4 If you have moved only a centimeter then second option The answer will be that there may be many children here. spread out Oh man it's again Pal B option will remain, let's wait a bit, Poll Sir, people must be doing it right. Hey Dinkar Sir, I can't see the chat here. than you do Yes, option B will be your correct answer. Okay brother, we have the next question. Zero Students Have Enjoyed What They Are Saying come here I want it brother, tell me the incident in this. Reflected Ray and Outworld I wanted to see how many children there were today. Yes, some issue has come up, let me fix it. It comes in the class itself, come on brother, the issue has come. The incident is as ray-reflected as the ray I told him once that sir must be listening there. But sitting there, Sir, I asked him as many times as I could Technology is good to come here Have you given the words, yes, they have been taken from the heart Correct It has not reached the children anyway What should we do now, our daughter should be more and this would only happen in my class. Sir came to me and showed it to the whole class. It is performing very well This is what I'm happy I said it was right. Friend, sir, after coming to our class, no one has done so much Techno guys haven't done much promotion. Whatever we have done, it is fine, you guys are famous. It may be in the name of Techno Guys but our Come on, papo, in class, no one is doing it. It's okay, the incident is reflected. Ray and outwork are denoted by dekho What did he denote Incident Ray? is a vector from right to the reflected ray They denoted b from the vector and They denoted normal with us is c vector to then choose the correct this your vector form so if you're missing Incident Ray is Equal to Reflected Ray Plus two voices of odd We have n in n cap, yes that's it You had to put a value here, so here it is. Son, your A vector has come, your B Vector plus tva of ad c in c vector If it comes to us then if you talk about B If you bring it to this side then fourth option We will have the answer here, option D. is going to be your answer clear very good Next question, please listen to my input carefully. Two bodies A and B are moving Towards a plane mirror with speed and b Respectively sh in the figure the speed of the Image of a question listening The speed of image of A. Theek Hai With Respect To B.B.K In respect we have to tell you okay BK We have to tell all the children in respect I'm drawing this diagram here. I need some space now, all of you kids. Tell me that this object was going Look carefully like this, it's going at n angle theta with normal this is your here I If I talk about it, it is normal for all my children. tell me this is angle theta If it happens then there will be an image of it somewhere. And this will be it Uncle, the image will be the same and yours will also be here. is this is your be this is going with like This is very good, listen carefully and ask what is it He has asked the speed of image of a Whatever image of Okay, its speed with respect to be It is very difficult to read the question asked. If it is important then I did it here, friend. Look, this will be your cos theta this will be your san theta Son, if your object is going this way then Your image will also go this way, so cos theta is If psi theta is here then the image will also go here. must be sine theta here if you If you add both then it will come back it will come v it is going from b it will be going from If so, the velocity of image of If you talk about A with respect to B If you do it then it will be very bad Yes or no, it's a question of kinetics. Your first option is going to be Answer A option your answer will be clear yes or No clear very good next question we have All the children please look at this thing, rotation Wala question for the arrangement shown below Determine the angular speed with the The reflected beam will rotate okay reflect beam from which omega You must be roaming around to see what they have given you. You rotated the incident ray by 20 rps The Clock You have rotated the wise mirror by 10 rps clockwise direction of the image or reflected ray Remember what the impact will be if The object was rotated to say the object I mean, if it is an incident ray, it rotates. Let's talk about image, Omega of Image what will happen are you remembering the opposite direction when you move the object Used to rotate the image in the opposite direction If the same omega was rotating then it would come -20 Come Pay dil bana beta iss baat very good love You son, if you are able to understand this, sir This incident is going around, hey incident ray means object and what where comes from comes from object so if your The object is making 20 revolutions per second. If your object was rotating like this then The image rotated like this, both of them rotated like beans If the value was the same then if this clock If I talk in wise sense then it is called minus Meaning if we have it clockwise then in anti-clockwise direction Ghumega with 20 RPS Say yes very good mirror if you turn it clockwise You are rotating in the sense, okay, mirror if Yours wa sense me ghum raha hai with 10 rps yaad If you do it, we will have the image in the same direction. will rotate in clockwise sense will rotate with two Multiply speed 20 rps to very Good, very good, this is what we talked about. If you rotate the mirror by theta, then image 2 Theta will rotate in the same direction, so its If it is omega then its 2 omega will be same In the direction, two are placed clockwise. Multiplied and placed anticlockwise Keeping the value same, if you keep both of these If you add then see click anti clockwise 20 RPS clockwise 20 RPS No Net Revolution then D Option is your answer coming It will be clear, yes or no sir, the question is wrong. Very good, you go in a different direction son. Whenever your NT paper is made, it will be given to you. The paper must have been given so that you could answer the question. Other children will find the mistake and answer You will find out the mistake in the question okay next question okay a boy is walking Under an inclined mirror The boy beneath her is moving forward I have come, this is an old question. Okay, at a constant velocity v Along the x axis as shown in the figure if The mirror is inclined at an angle theta with the horizontal than what is the velocity of The Understand what will be the velocity of the image Here is the diagram, so these are your options. Yes, let's look at this question. Children, please help me in this. we had this we had this okay We have your mirror somewhere, son. nowhere like this okay this is your The mirror is No, all the children, please watch this thing. If my object is in this direction I am moving at a little speed If my object is this Moving in direction and at speed OK If my object moves at this speed is moving in the direction at an angle Theta So do you understand this thing that The image will be at this angle theta. I will I'll delete it for now, okay, the image that It must also be going at this angle theta like this Yes or no, all the children will come to me first. tell me this yes and No, yes, or Na ek bachcha tab se laga hai ending date of Course son brother whichever team is looking back Sir please block this person, RJ Block name That's it, get him blocked Yes, you can do it another way. I wish the calculation would increase but see Object distance zero then image distance Zero as you move the object This is how far and near will be, the value will remain the same. is again b He plotted the x-axis and y-axis Velocity in term is asked yes so are you We can say that this one from horizontal The angle will be 2 theta, right, because this So this angle is 2 theta. If I resolve this, it will be will come v katu theta beta and here your a This one will go, the value that will come is this v Saat If it is theta then your question is answered. gonna have that is v katu theta aa cap and v Sat Theta J Cap Kiskis Ka Ye Aa Gaya Dil make First yes or no, whose heart has come to this Make it yes Gaurav Dhaka son I don't care. It comes, okay, so what do you lose? study Here's your object: Image It happens here, it will always be like this. should always be the angle bisector so that If you have any line then this is its perpendicular bisector okay so I said if this is the line of the object then This will be the line of the image if this is angle theta So this angle is theta from the horizontal if you What is the angle from the horizontal? 2 theta so here too it will be 2 theta so v cos2 theta v sin2 theta just give your answer will go v cos2 theta aa cup v cos theta h cap Fourth option that is going to be Answer Clear, clear, very good. My next question. attar punter ok this is in recent year also You will find this is a repeated question okay is a point source of light b is place at A distance A okay one B is this L Distance lies away from a mirror whose The circle is placed in front of a center of the mirror of width and hung vertically on a wall English is a little dangerous, man walks in Front of the mirror along the line parallel to Mirror at a distance 2 a from it as shone the The Greatest Distance Over Which He Can See Image of the light source in the mirror first All the entrants who understand this thing If you could not find it then tell me that first English first Let me explain, first you need to understand English. It will be necessary, son, for all the children of class 10th. Please get out, it's my request, okay? Clear the paper when the time comes. If you don't have time, go and read it. Many people did not understand this at all Let me explain this first, as if to understand that brother a mirror Okay, the length of this mirror that he has Given that is d one your l here No son an object at a distance Okay, at your L distance, there's one If there is an object then it is obvious that as much as The distance will be the same as the image behind it. Distance will be Pay yes, now suppose this is a mirror There was an object, then there was an image in this mirror It must be ready, I am starting to walk from here. If I am there then I always tell him how far away from this How far can I walk in that direction? that the image I have of this object I will be standing here and still I can see you It is visible here also, it is visible here also I can see that I should walk here so much that my The question is that he should always see his image. Do you understand what he said? And a man walks from here at a distance remained okay so now look at this like this Even when a person comes here, he will see this image It will be visible even when this person comes here It will show the image of this person here Even when this person comes, the image will be visible. He will see it even when he comes here. Even when a person comes here, he will be shown the image. What will be the length of this Ld that she will give it Can you see if you understand Question: Yes, those who need a break, you can take it. Okay, you won't get any break, but it's okay. Firstly, it is a big chapter and on top of that, it is a mental mess. Give them a break when I have to. I will give it, okay, otherwise I will leave the topic in the middle. If you want to leave, tell me brother, it's just two minutes away. You will get a break and the exam will continue. see you after Then what is Question A saying to this now? See Son, when a teacher is standing here, it is no less. Do at least this much, see if you have words You can't write anything, but you can speak. No, you can at least type it. Respect me so much that the other person If he is teaching then he should continue teaching, that mind I came from to teach, okay, that's it. If there is an object then the image will be on that very point and What you think is that if I write Maybe sir will give you a break from this, son, when you give it I will give it to you only if it happens. Sin goes away It's okay when you hurt someone. Definitely a part of it back to you I am telling you this first, you get it in life I am fine It is returned to you if you give it to someone intentionally Or if you hurt someone unintentionally If you deliver it, the share will be returned to you. It comes okay so try that anytime you Don't do anything that will bring you back You may have to face what you have the courage to No, okay, let me see this. If it is not there then I will remove it. I wanted to see its image, so I said, friend If this guy stays in this region forever You will be able to see his image by answering this question. has been repeated many times If I will always be able to see him then this distance was your D I said okay this distance is yours 2 So I said, friend, this is a simple matter. As long as he stays in the region, he can easily If you can see then a b c d and e you triangle talk about abc3 is a similarity so sides are in ratio Son and sides will remain if the ratio is you perpendicular side you could say I I will mark this also for some children. for e f g then of the small triangle The ratio of A and A of the larger triangle If the ratio should match then this is your How much is it son? How much will it be for you? 3l okay talking about Basi then d and this value Let's take D, so if you look at it, D is equal to T 3 times of d this much distance you will have Look, it's called geometric optics. If you have to take care of C geometry then 3d fourth option that is going to be Answer Clear Very good, love you son, next question a little more. Children, tell this on the day of exam The children will spoil the number of What should the images be? think think think Think number of How many images should we have? Children will say, Sir, this is a plain mirror. Sir, there should be images for two questions. Please mark this question with a star somewhere. If you come, spoil it okay will you give some kids infino Listen carefully son, whoever is from here The light is coming out sometimes on the other glass If you don't collide, you won't have multiple images. becoming The light that went from here and came back here The light that went out will go away like this, son, if you If we talk about their images then here you will find i2 mill Whatever this race goes through will be cleared. It will also go like this if you look at i2 mill This ray will never go on the glass This race will never collide on this glass If they collide, the multiple images that were going on And it will never happen, the answer will be yours. First option that is This is very important to remember Because generally children make mistakes in exams. It happens sir when will there be infit images Its ridges are parallel to the axis Wherever your object is, then your Infit Images will remain Clear love you son, this is your question Let's see if there is zero in the pole. Yes it has come it has come it has come start poll Let's write, write, write, find the number of Images Formed Option You have to write Tooth 4 I don't have to write this number, okay, yes, poll. It's done, now let's start, write, write Write, now many children will see these two sir mirrors are perpendicular Listen carefully to this case and this one. The case is very different How is it sir, please look carefully if your The object here is this light race, if you If we talk, it came like this, it went like this. This mirror gave an image that came and went like this. Suppose you have made your own mirror here. This mirror is your one, so this mirror was made by two The image OK This is very good, your light went out here, so this Come back, this light went here, so this If you go here, the image that will be created of you is iOne is okay or I by Mirror One or Mirror One has created his image Made it clear sir, there are number of images in it. formula for number of images If you look, it used to come Sir, there are actually only two images, this one There is a portion where the light passes through and collides with it. Then it goes like this from its intersection If you look here is your third image. Banati From its intersection, your third is this third The image which is this image mirror one and mirror two making a combined When both are being reflected upon When there is mutual reflection then third When the image was created, this formula three came into play. But my enterer if you here You will see that the light goes on like this and goes off like this. If the light goes like this and goes like this then an image will be created You can find it here This is by m2 Lite We will talk about you here, son, this is how it went and The light will go off like this, it went off like this and it went off like this You will get an image here by mirror One because the lights in the middle never meet each other If there are no reflections then there will be no third image. If you get it, your answer will come in the first option. Your answer will come first option son, hey friend Poll None First Option That Is Going to be r answer ok next question sare The child is not coming well, what should we do? Brother Let two objects A and B be placed at Distance 15 cm and 25 cm from pole in front of concave Mirror is ok All children have to maintain concentration whether you Thinking about the approach at the last moment A is the object and B is the concave mirror Having radius 40 cm for all children Making a heart will help you focus, Sir 20 centimeters so I'll take a value here Let's assume there are two objects, one 15 On a centimeter, somewhere here and one is at 25 centimeters so B is yours will be here Okay, the distance between the images form By the Mirror What will be the distance between these two? Who can understand this? you have to solve for A separately will have to be positive direction so the value of y if you look at a will have to be solved separately that is -1 f value of -20 to 1 up f e equ up v pw up y to What you have to do here is -1 ba 20 ive up v And -1 is 15 so 1 is equal to you. to us / 15 okay minus 1/20 will come to us so v You will need a different I will get the concept and tell it with my heart and sir Let's solve for B separately. Where will he create his image? If for B If you look at 25 focus your minus 20 so 1 up f ive pvi love you Let's see who can grasp the concept of yes or no. Brother, create a different image of B. Create separate images and the distance between them If you measure, I'm placing a sign here. You have to solve it son, this is your homework okay my ba 25 we have so 1/2 P 1/2 Now you will solve this and then We will find the distance between them and No Ha Ya No, yes and no, did you all children see that what is the question in jee mains 2023 brother Merging two questions of class 12 into one I have made a question, make a different image of it. Make a different image of it and solve it. Please clear the next question See next question Square A B CD Side 1 millimeter is a square of this AB CD Its side is TE 1 Millimeter is kept at distance 15 Centimeters in front of concave mirror beta All the children, yes, also keep telling what You are able to hit the concept concave You have placed a mirror whose focal length is How much have you given 10 centimeters Okay, the length of the parameter of the image. will be approximately, let's tell you now What concept will you apply? All of you are telling the answer, the concept Tell me what all the children will wear Question Y is saying that your concave mirror Is Son, okay, you have a concave mirror. I placed a small square on the 15 distance in centimeters But okay, your focal length is 10 centimeters. The concept of telling the length of the perimeter is What will apply magnification Very good, very good, all the children, just look here See if you talk here this 1 It was of a millimeter, so I say its For this the value of u is -15 and the value of f is If f is -10 then 1 / f = 1 / v + 1 / u then this will go son - 1/10 this + 1/1 = 1/0 and if If you take the LCM, son, you will get 30, so -3 The value of +2v is coming out to be -3 Is The value and perimeter of the nail have been carefully asked. If the value of v is y then you are lateral If you talk about magnification, it Height of image by height of object If it is then minus bound then I said height of Image is equal to your 30 value I want it and the value of y is 15 1 AA then 2 AM then height is done Whatever image is created of this, understand it carefully. 2 AM so its height is coming What is the width and what is the longitude? Magnification is the thickness of the head. Image by thickness of object minus v sba u s minus does not make sense because He will tell me the orientation, so I said, then this is it. The thickness of the image will be 4* 1mm so the width that is coming that is 4 mm that is 4 AM all the kids yes or No, this mistake happens brother, listen carefully. Its height will also be 1 mm, so I said I will find the height using lateral magnification. Its width will also be 1 mm. Finding Thickness from Longitude Magnification I will take cha and 6 12 perimeter if you will talk So this is your perimeter answer for 12 AM. If it comes, what option are we getting? Tell me the third option, brother, it is clear. Is 12AA going to be the Answer Sir, square will not be a rectangle. Trapezium will be formed but the thickness will be so small You can approximate it in millimeters. Can be considered square or rectangle Clear very good next question son okay Next question all the children please ask this See what the question says first. See two plane mirrors m1 and m2 is ok one Sir, please try it once, just minimize it. Don't drag it down, okay, let's go son. Let's do it like this once Start pole ok to plane mirrors A1 And m2 okay I made it two plain Mirrors m1 and m2 are right angles to each other Shone a point source pj place at a distance a and 2a a and 2a in this way meters away from mirror m1 and m2 the Shortage Distance Between the Images in This I got a bonus because the question was incomplete. But I completed the answer key. The shortest distance is correct according to the calculation Between the images, these are formed individually by Etch Mirror It's okay, the question was incomplete, so in this The bonus was to see if I was talking here. If I do that, it has created an image for itself. Three images are formed at a distance of It will have formed its image at a distance of 2a But yes and if you talk here it's okay If you talk here between these two Whatever the distance will be, then I am Pythagoras I can deduce this from the theorem that you have here Distance will come that will be under route in this The distance is gone, son 4a okay and this is 2a so 4a's square by squaring your 2a This is your Your distance comes out to be around 4.38 Okay, first of all, where should I put this pole? rotate okay so do you understand the concept It's okay son, we have a third option. That is going to be your answer hum ab aa gaya The pole is fine Let's put this here, okay, clear. Understanding the question, what do we have in Both of them made their tables between them. The distance of the short distance will be this okay so this is your 4a this is your 2 If you talk about the shortest distance So you derived it from the Pythagorean theorem Answer will be C option very good next question Okay son, give the next question in the new poll. I have been Let's see the variation of v vidy va and the graph of y is for mirror a shone in the Figure The curve is hyperbola straight line of Unit slope means 45 degrees. But you have drawn a line that intersects the Hyperbola at point A if the focal length e is 20 centimeter What is your focal length if it is 20 of centimeters, so tell me the coordinate of this A Give me the cosine of this A, now tell me this graph Also remember Even if you don't remember, use common sense. This is the line y = x Isn't it true that the line y = x has a point Think about when v = u is the image distance. When is the object distance equal to When object is at c When object at If we have c then the value of u is yours So 20 cm will be 40 cm. then the value of v will also be 40 cm Because the slope is your forest, so if you look So hey hey hey hey hey two will be okay so second Your answer will be option B or second. The Option That Is Going to Be Yours Answer very good, the raita spread, it spread fine Listen carefully to the y e x line and y Equal When are v and y equal? ​​When is the object If it is at the center of curvature Object Center of Curvature at Object What will be the distance? If 2f is 40 then v is also 40. This is the coordinate It became clear, my next question was like this: The JE did not ask the question but I wanted to I hope you solve it properly. So I'm starting with a little bit of it. It will take some time, okay start poll Come on, let's C brother, listen carefully to these three Dimension Coordinate System O xva h ye A good level question is a concave mirror of If the radius is 40 cm, then your focal length is We have radius of curvature so focal 20 centimeter this happened an object place at Origin gives a given velocity so find Out the magnify of velocity of image this question I will not get polled, son, you can do it in the comment chat. I will comment, okay, I will comment in the chat. It detects itself All the children will first answer this question very carefully. Look carefully near this particle Eye Cap There are 6 J caps and 3 K caps, I want to tell you all I would like to ask people that it is an obvious thing Sir velocity magnification question can you tell me what is in it What magnification will you use? Lateral or Longitude first this question tell me speak speak speak my enter Painter, all the children, first tell me friend The velocity of the object is given in the image. If you have asked the value of velocity then firstly I should know this magnification one If the question is Yes, now you have to remember this, this is The principal axis was for the son not the one Yes, which magnification letter or Longitude should now be understood for this You A Longitude Use For this you will do Longitude If it moves along the principal axis Longitude magnification is Perpendicular to the principal axis Near lateral magnification is used by you I had to remember this first Along the clear principal axis Longitude Perpendicular to Principal Axis Lateral Ye I can remove lenition and lateral only when I know If we talk about u then it will seem If the focus is -80 then -20 then 1/f = 1 / v + 1 / u Look carefully son - 1/20 This + 1/80 = 1 / v is your LCM Your 80 will come to -4 + 1 so v that if you If you talk, it will come. 80/3 yes or no all the children first thumbs Please tell me if you got this thing sir v If the value is y, then I will see lateral magnification If I take it out, sir, this would have been minus of v/ u I said yes sir minus of v has come - 80/3 and you sir yours was -80 so this is it Sir, 1/3 came and the tunnel is of this only. square is the minus of a lateral Square so if you look at it it will come Minus ofv Bana Love You Son, first of all, brother, it was a question of class 2nd. Even the davi is going on here, brother whose thumbs I am coming down, I have driven till here, then I Both magnifications were taken out, lateral and Longitude will now become a question, listening attention The concept was that the velocity of Parallel to principal axis is nothing Butt Longitude Times of velocity of object parallel to principal axis so along x just look If I talk about the along X axis, Velocity of Image Kya Aayegi May Bana In 9 I cap toy aa jayega minus aa Cap Clearly, just look at the velocity of the image. Perpendicular to the principal axis or lateral If magnification was used, the velocity of object perpendicular to principal axis So along wa axis jara Let's see what the velocity of the image will be. Magnification into velocity of object along wa kitni hai 6 h cap or aati-2 aa cap vo-2 j Cap clear son please hit the concept I've been watching the kids from the start All the concepts are stuck and will be revised. If I talk about along the z axis Son, okay, so this is also perpendicular. If the principal has lateral magnification If it will be used - 1/3 is fine - 1/3 z of along velocity How much were your 3, son? Cap My Kay If Cap asks you a question, Velocity How much is the off image, so I would say minus a cap -2 h of cap relative velocity of cap my If it were a question, I would have applied relative velocity. Give me some magnesium If you do it politely, then everyone will keep learning. These things will go to you These were sexy questions, I thought these were you If people do it themselves, this is your homework. Please try this, okay please You should try this, velocity velocity All these questions of yours are in the next part. We will go in I will tell you in advance when I will give you the refract. I'll give it to you okay so that before that It shouldn't be inside Let's talk a little bit about R and reflection. Then after that I will give you before the prism I will give you a break then prism and lens wala We'll finish by parting, okay? Before that, if you take a 10 minute break and If you need it, I will give it to you carefully. Listen clearly, let's see who the leader is. Hey brother, our Pass because our polls did not happen 15 There were questions, out of which six to seven questions were not answered but So far in seven questions, Melody so much Melody Why is it okay, so this child has done it very well Hey, where did our first topper go? Son, where have you gone? This is what consistency is all about. Let's see if we can find out the melody till the end. Whether he survives or not, Arihant Jain's rank is high. Hey brother, very good, tell me something about rank up. Okay, Sintu Chauhan's rank has also increased. ok son, there are more questions to try that you should go upstairs only, okay then Prachi Maje Mandeep Singh and many other children's ranks His rank has increased but has fallen Vikas Sharma ok or maybe it might have fallen All the children, sons, come to you. It seems like yours is not coming, it is not like that ok this is for all the kids As many children as will come, they will keep answering. Oh dear me minimize ok OK Yes, many children are answering But our top kids are fine If so, he is Meldy, he is Arihant and Sintu Chauhan Hai Reflection Part Tak Melody Ne You have done it perfectly, okay, one question. It may be that it got spoiled because of me. I must have moved it here and there, it works fine. All the next children will tell me this Tell us if we're going to have polls now. If done correctly, we have a doti 3 4 pa 6 Sa 8 9 10 11 Some of this is subjective too I'm assuming there are seven questions. More objectives are coming, let's see. how many kids make it to the top 10 okay Let's just look Yes, all the children should now study properly. Refractile moves from one medium to another Well, let the path of light always be bent. I remember what I need to keep first Once I write it down, I'll tell you Hash. He writes his notes and only then you get that point. It will be saved, okay, now I will write it first. I take it when I say, son, I have written it down. on this whole then you save it ok Look, whatever we have, the frequency of Light is the frequency of light. It always depends on whom, son, it is yours. It was source dependent Okay, it never changes, never. Things are fine, never change I never change anything once I Source has set the frequency, okay? Sir, how to save it, if you want to save it Son, you will write more such notes. Will give these in chat If you do this in chat, it will be yours. It will be saved where will I be at last And I will tell you more These lectures will be held at Unity D Padla. All the short things you have, all the things you will get it okay good what else was it There was one who had doubts, many people also watch it. The children must have asked their doubts. Look at this angle, now I will tell you this also. I am watching what some children are doing. I am just writing this If there is any doubt, son, writing this will not create any doubt. Next to this, write your question. What is the question? If he writes it then It will come, okay son, if the object is yours Look, if it is even then the angle may or may not be there. No Matter 360 Ba Theta Mov Images When it comes to odds, they will be symmetric 360 ba theta myo meaning will be for you Angle bisector p and if is not an angle bisector p so 360 ba theta okay this See, that's why I'm not opening it. was fine Hey Lad, the tech guys told me this, sir, yes Look, this is the problem, he said the video just now will work No, I wish this father's number was fed. Call I do that, so I know the kids are writing. Doubt is why I want you to chat about doubts. Write it down, that kind of spamming is not happening today. I am very thankful to God So that such children do not trouble you too much. who are normally sows fine He is so thankful that he has just proposed to someone. It has been done, it may cross the limit, okay it has crossed the limit yes Maybe yes Dinkar sir if you are listening We have a police force named Police ok I will tell you because salary How much technology will have to be justified If you do it then make one called police. What is there in it that they talk nonsense about us? Isn't it a comment, basically the police should catch him? okay some technology in this think Because look, this is the only way to stop spamming. If there is a way, then the police should create such a project. Get three or four techno guys together and get the job done. Start it, yes, because in the homes of such people It is very important to reach there and kill them. Later, you can file a false case. If he gives it in the society then Papa ji's name will be spoiled. They should be caught first Yes, come on, light son, when from a medium goes to another medium okay we yes When light passes from one medium to another goes then we always have frequency Everything remains the same, what changes son? All children, please write carefully, velocity and wavelength of the light changes velocity End The wavelength of light, son, is ours changing the pass The velocity and wavelength of the light changes So that's why we had a term. If you are missing Refractive The index will now go to that diagram first. Refractive index, which you can denote by There are two types of these, son, one There is absolute and there is one with relative attention Listen Refractive index is the ratio of the speed of light in medium to the speed of Light in vacuum to the speed of light in Medium, you call this absolute Refractive index is the value of m That is always greater than and it is always one All children are older than this, please note now Don't do it when I say I've finished it. Once you've written it down, you can note it down. So this has come to us relative What is the refractive index? It is relative when light travels through a medium and If we talk about other medium then we will People talk like one and two when the light Moving from first medium to second medium If yes, then you write u12 this is the ratio of refractive index of two with respect to one so this is c ba v2 in c ba v1 so this comes to v1 ba v2 ok here you go son v1 ba V2 Remembering Relative Refractive Index Me and Me Not B may not be greater than And it can be bigger than the forest and smaller than the forest. It could be smaller, it depends. Absolute refractive index is always Greater than one second thing in this formula Let me change one more thing: the wavelength. I will also put the term which is yours absolute refractive index that is c / v Equal to frequency never changes If it were, the frequency into wavelength in vacuum divided by frequency into wavelength in medium so this Ratio Hota Hai Lada Na By Lada Medium Ka Bhi You have also received questions on this. Always greater than and clearer than There are children, please keep the focus whenever the light When it comes from a medium, this is your Incident Re, this angle is the angle of incidence. Whenever light passes from one medium to another If it goes, it always goes in its direction. It bends, it should have gone this way but It may also be away from the normal. We can also have from normal, okay So the bending of light that has happened, this is Your refracted ray and this is your angle of refract this bending of light phenomenon okay phenomenon of bending off Light Bending Off Light, this is what you call your fraction so a refractive index here Take u1 when the refractive index If there is a change then we have the light with us. This phenomenon bends the path is called refract now all the children Note down the exclamation marks and write them down If you take it, your time stamp will be saved here. will go Clearly, the story after this is this. Understanding things is a law of ours If you talk about refract, the first thing Wait now son, I will tell you about this also later. First thing is incident re normal end refracted ray all lies in the same plane all Lies in the same plane, it is always in the same plane I would have brought it Secondly, it is very irritating to many children. I feel like myself a lot Snell's Law seemed irritating, so let's try this. The way to remember is simple, just assume The refractive index here is m here The refractive index is t whenever i I'm changing the refractive index. The means and medium are changing with us. If the light is coming from a medium, this is Your angle of incidence then light is with us When it goes to another medium, this is your angle of What does the refractive law tell us? It's okay whenever Refract law will say its refractive Index is fine, this is the angle I have Equal to its refractive index in sa Aa always remains constant in all children's hearts Make Did you understand this The Product of refractive index very good to the Sine of angle Sine of angle made with the Normal is always Constant Sir, when will the course end? Bachcha Bhai Saheb will never happen, it will keep going It will continue, when we die you will die This will continue, this life will never end. It won't happen, it will keep going, it will keep going crazy Humans are fine, remember the m*cy of angle okay sa theta is constant this is Understanding Your Snail's Law Where I'm More where theta will be less, where m is less There will be more theta, this will be very It is an important thing because you people I saw this in 10th grade. Whenever we have light rarer to denser caste Whenever the light goes rarer to denser Angle where refractive index is increasing If it decreases then there will be a shift towards normal goes and whenever The denser the light, the rarer it becomes. Do it okay whenever the light turns on your dancer rarer goes where refractive As the index decreases, the angle increases. So shift away from normal, something like yours All the children make a heart and then its Taking a photo is rare to Shift Towards Denser Normal is fine and denser to rarer shift Away From Normal Now all the kids take a photo of it. Take it Hey brother, who is here, what happened? Live is over How to Snap a Page Brother, there is a lot of fluctuation in the class. and WiFi Yes, my son is coming to you guys. Asking for a lecture or hot water speaking lukewarm water brother yes it is coming to you okay my That lecture flew past me, I thought somewhere It did not stop, okay, at least once in my mind Hey, it's a holiday I will read the rest of this some day but the rest You left again, no one was walking in you Oho Dude, no one, no one, absolutely yes Our motivation is not down at all. One day, I suddenly got tempted I never lied to you, okay, just once. So I also thought that the whole thing has stopped, let's go. go away The house will be inspected tomorrow, give it two more days. Aunty, I gave you an extra day yesterday. I will teach you, but suddenly and refreshingly If you press it, everything comes, okay, no one, yes, okay. If yes, then it comes first in your syllabus. slab Yes, okay, it comes first in your syllabus. Slab work is nothing but Can shift, only shifts be careful Listen, he will come twice and get the shift done. He also has a father, okay, father of the club. Many people enjoy it, we show it to them. If children joke in class, He says what are you doing like this, right? Where has the father of the The slab has arrived in 2021, this is the slab Abbu is off the slab Abbu is coming, he has come Bhaiya also came to the class for JE Mains when If you teach, children make fun of you. By saying Abbu Abbu So when he comes to the exam, he says, "I am The Abu Now okay so this dialogue to you heard in the background If he gives, he can only shift the slab. Okay, but convergence and divergence Power can also be if you are plano concave and merging plano convex lenses If you make Abbu of the Slabs, you It will be visible, okay, yes brother, just look here. Lateral shift derivation from is not for you Okay, if you have any thickness Listen carefully first I will I will explain the diagram, okay, derivation. No, but we are talking about ray diagrams. Let's say I have a The slab is a glass slab, this one Thickness θ t Refractive index θ I am fine We're fine, now let's take a closer look here. Whenever you want to make your light source diagram Make it exactly as you would by hand. The more you make things, the more you will remember them. or angle of incidence this light our If I came near, the light would ever become rarer to denser If it goes towards the normal shift It will go something like this, son, the light has to go where should I had to go here, this is initial direction of I Initial Direction of Incident race but light like we have here You have to look carefully son, when the light If it emerges from here then its absolutely Parallel comes out to us okay this Is Your Emergent Re this is your angle of emergence e this is This is your r, look carefully, hey Hey, stop making it completely. Let it be known that you are going to attend the lecture. I made so many notes, completed the entire chapter. The video is playing when the important thing comes After noting it down, he sat down lazily at Bakul Dar. Yes, please remove it sir, see this option. You have been wearing this shirt ever since you were born. The video will play later when the child is looking at the notes If you click, Rajvan will appear like this every time. Nothing else is happening brother, this is a big nut. or putting exclamation marks notes then I saw something important, now this is also your matter. That's right, everything is important, read it first. No, there's something there, father-in-law No son, stop, stop, stop, okay There is so much hang note suppressed there website will go down Brother sir, please give me at least five, Dinkar sir Listen to me, if they have 10 topics then 10 Just don't give more than that for notes. Otherwise, brother, this will increase your work and We will make it crash and then invest the money and Then they will say that even for free it doesn't work properly. PW people are doing it yes ok Come on, this is emergent ray and initial These directions are shifted among themselves. is called lateral shift okay this is Called yes, I will count 8000 crores, okay? So where is our money going? Lateral shift we have this, just like this Imagine if you were to apply Snell's Law here. You say 1 * sa aa is equal to m n sa aa says Son, if you had applied the Snes law here, the same thing would have happened. I say I come like this and if the medium here and The medium here is bean, be careful Listen, the medium here and the medium here is the same If this is your 1 in sa e then your attention would have been It is very important to understand Cheese if both sides are medium your beans The medium here and the medium here is the same Angle of incidence is equal to angle of Emergence and this light we have laterally It shifts, okay, this light is with us. laterally shifted Brother, you try drinking. Don't gargle this, my son. He brought hot water again. OK So your lateral shift is Whatever the formula, the children will be from the board He must have read these with derivations sine of i minus aa divided by cos Now I can teach my children in a very good way. when I'm writing formulas Then it must be coming from inside them, sir please Explain by derivation from basics be a double I don't know the spelling of SC basics but From Basic Tell me, when you were doing derivation in school Then Sir, we understood a little bit from this question. Can derivation to threaten tomorrow sir we have experimental If your mind is okay, then your lateral shift would have been is it in sign of a mine and your Thickness is the angle of incidence and our Pass angle of reflection at its cos Oh, there is a double-headed snake, a two-headed snake One who has two faces and one God A snake behind Lord Vishnu I am forgetting their names. The children have become so involved in spirituality. They want to keep it straight like that Yes, the one whom Lord Krishna killed in water I can't remember Sheshnag Yes, children have such big mouths. No brother, Sheshnag while teaching Yes, when you do the derivation then sir question Please ask the question, then tell me the derivation sir Hit the teacher the same way Diyo Yes Yes, now please understand carefully here. This is your reflection slab so far. We have just one more normal shift We will talk about the slab later. That's all for now, next important topic ETIR Total Internal Reflection is fine Even Shesh Nag said seeing you, oh my god How did the child get such a big mouth? He also said, brother, I was Dashanan and you were Sanan. Yes, your mouth is everywhere, you talk differently remained Child Understanding Yes Total Internal Reflection Meditation When Ever Light Goes From Denser to Rarer There is always a condition for this, brother, whenever the light If yours moves from denser to rarer side We have found that a particular Why are you laughing after this, when laughter comes only then When you can really feel that thing So I am actually making fun of you and When I'm making fun of you, you know it. It seems that it is correct No, whenever the light turns off, son, you will question it. Then we will get a break. Okay, all children, attention. See first whenever the light is denser than If it goes to Medium then it shifts away from The normal, you know, all the kids just look carefully here Let's say my light is like this This light was like this, so in this case the angle of What is the incidence of all children? Tell all the children quickly, if the light It's coming to us like this, so the angle What is the incidence of 90 degree is O Lord Jagannath, take away that one, O God This is not a meme, Lord Jagannath 90 degrees is speaking Brother, I want to send him to IIT. I feel demotivated after seeing you. getting Let's do 90 degrees Brother, please send me your email after some time, Rajvan. Sir, he is a very good teacher, we approve of him. I will do it, okay, we will approve it, yes. We are we cannot teach the angle of in here I am standing at 90 degrees, so say it's fine. Next, brother, the angle is measured from the normal Yes, that's right, the angle is measured from the normal. The angle of incidence is zero here, so the angle Even off-reference your light will remain zero just like this It will go away, it has been made crooked and the hand is a little Well, it's okay, but the light will go like this It's okay, we have light something like this If it went that way, I would have written it here. I am about it First case, if your angle of incidence is zero then angle of It is also called refraction, okay, we They say Normal incidence carefully Look like now As soon as you see the light at an angle So you know the light is denser to rare If she is leaving then shift away from the normal then I wanted to go here but what would the light be like? Will I go somewhere like this? If the angle of incidence is increased further The angle of refraction will increase further. Do you think this I understand a particular angle You will get it when the light falls on it from the surface like this She must be crossing yes or no, yes and no in this This angle is called critical. This angle is critical Condition this is your critical condition which light The angle of refraction is 90 degrees. The light would have come out just by touching the surface is this called the critical condition if value Look, I took the angle of light off this. Incidence exceeded the critical angle This is the notation of the critical angle. This is your theory. It is C son, so I have calculated the angle of incidence. Greater than critical angle to light It is reflected back in the same surface It goes perfectly on this surface. Reflected back Complete Reflected It completely reflects back in denser Medium okay this is what you call TI R Total Internal Reflection What is this thing I understood, all the children, make a heart once, yes Or don't look at it brother, please understand the condition. If it was normal incidence, the light would come out like this If I go to the angle of incidence here If you increase it, you also know the angle of Refract yours This will continue as I increase the angle, sir. Why is Light Denser Too taking so long? Raider Goes Shift Away From the Normal As I increased the angle, it A particular angle of refraction will occur when The light will travel here touching the surface. What is the angle of refract here? 90 degree is son okay here your angle of How much refract is 90 degrees then this angle is what we call the critical angle if your angle is greater than critical angle hota hai Only then will your light undergo total internal reflection. It finds that the light remains inside the medium. is this phenomenon called sir i mean when Will Manzil 2024 Will and Ye Laga Pada Ek Brother, listen carefully to the question, is it today or tomorrow? It is possible that we have taught as many topics as possible. I will teach you till there, if there is some marathon then it is okay. Complete whatever topics you missed and complete the marathon. We will get it done from A and then JE Mains One. I will see you later on the topics I missed. My power is pending, then this JE will run again The series will continue till Main 2, Prabhu. let's go Let's be clear, this is what we have, so now we'll talk. How do we find the critical angle? If yes then brother, please understand that we have eight critical angle Okay at critical angle if you talk okay then you Snell's Law can be applied, so refract So it is still happening brother, so the condition of Critical angle we have the calculation of Critical then this rarer medium considered necessary There will be air and this is a denser medium If you believe then critical angle will never happen to you. If you want to remove it, your light will go, son dancer Too rarer first talk and Snell's Law so you can always apply Snell's Law if you apply D*s All the children of Theta C should I make a heart once? You get it, d*s theta c equals tm Rer in sa 90 you will say here son sa 90 is one so the C's if you talk about Critical angle yours comes sa evers of m Aa Ba Mdi Son, generally if there is air in your question Rare Medium then you must have read this question The critical angle is the average of 1 by 1 You might have read this, yes or no, now you should note it down. If you want to download it, please take it down. No problem, yes or No Yes and No Clear Sa Years of M A/M D Those who have this confusion in the formula Na always ki sir / mdi tha mdi ba m aa hey Brother, just apply Snell's Law once. It's over, clear love you all, now that's all the story. But we will question Sir, this is very What do you do if it's a short story? He will forcefully add story to story. Let's say we have 60 seconds. I'm giving you the poll, just watch this until then. I take it you haven't written any answer Ask the question, yes ask the question here The answer is written, okay, so let's move on to the next one. I hid the answer before the next question. I will not take it, brother, he is a very smart child. Let the light propagate 2 centimeters distance in glass of refractive index 1.5 Okay, I minimized the poll. I don't know whether the poll would have come or not. I'll check it once, is it okay or not? It will spoil the children Then let's see Correct Minimizing was causing a mess Let's watch Light Propagates 2 centimeter The son is in a medium whose off glass Refractive index is 3/2 in time t na to yaar dekho speed is Equal to distance upon time hota hai If you have a son, then whenever your refractive If there is an index, remember refractive What did the index formula tell? This is c BaV in medium Velocity in this medium how much will you get that is c ba I can say this will be c Divide by m is 3/2 equal to Distance is 2.5 divided by 100 Can am in the same time t no light prop at Distance of 2.25 is another medium, son. The length in this is 2.25 9/4 centimeter, I'll say it here. okay its refractive index to me u know means i don't know time it t If it is not installed then even in this if I try to speed up If I talk then your speed will be c/ba m E equal to distance is 99/4 t Neither has this come nor has the question said it. That's what I've done in any medium. If you go brother, the speed will change, so here But what will be your speed c/m then I where the value of c / m is 3/2 2 3 this also Keeping it in centimeters, this is also in centimeters If you take the ratio then there will be no problem, okay? So 2.5 ban is not here also so if I If I take the ratio of both, it will come to 2c. 3 Okay 2 Sa Ba 3 And it will come son C The balance is 5/2 2.5 so I'm going to call it oh this What is 2.5 from? Where did 2.5 come from? This is 2 centimeter is 2 divide by t Isn't it 2 divided by t No, yes, okay, then 2 divide by 2, son. Here But and its will come 9/4t neither cut now Let's do PT, son, we have C to C gone t no to t no went this two and two This is gone, we have three of them. The value will be coming to you Your A option will be getting a value of 4/3 Yes or no is an option I hope oh God hey Prabhu yes very good very good an option that is going to be your answer well so in this Brother the answer is marked, okay first of all I would erase Yes, it's okay to stay here Yes, otherwise the child will sleep a lot. stay yes Correct This is the type of question in integer type my enter punter okay so I'll give you time I'll give you 90 seconds, okay, start. Oh friend, I have minimized it. Hope it doesn't get worse, okay, let's go. Yes, let's go, let's go and observers can see through a small hole ok on the side of the jar of radius 50 cm at point of height 15 cm this is a rod this directly If you are looking through a hole, it is 15 cm. The radius is 15 cm at a height of Easily visible from the bottom sea Figure the hole is at a distance of 45 What distance is this in centimeters, son? It was 45 centimeters tall, that's fine. When the jar is filled with a liquid up to Height of 30 centimeters You have 15 centimeters here so 30 centimeters when it is filled with water or Liquid filled The Same Observer Can See the Edge of The bottom of the jar means the light below Meaning if you can see the bottom then 30 centimeters what have you filled feed with The Refractive Index of Liquid In ba 100 value of an integer you get Narrate Okay, let's see as many children as possible. Honest children, which ones are in this question? You can let me know if you are having any problems Because there is something here Leave it, don't be afraid at all Son, it's okay, you can learn comfortably because Your Learning Graph is Important 15 centimeter They have filled water here, so this E again 15 cm or water or liquid whatever it is and 15 centimeters from here and up You are looking at things carefully Look Okay, all the kids, please look at this thing. He was looking at things from here, so he What did you say about the bottom light? Correct that There is something like this Is It's okay to understand that all the children who are honest I will help those who are having problems. I'll do it, someone was watching from here He When you measured 30 centimeters It is fine when you have done any work up to 30 cm. If the liquid is filled then you can fill it till the bottom. Can you see why this would happen? understand whenever Light was what we had before, directly But as you did with the liquid, it was rare. To make the denser light shift from the shift towards The normal Y will be going down further then Actually, this story is coming to us. Many children would answer yes or no. Its refractive index is U value I take it and I made the diagram like this But I make rough okay because You should understand that this length of it is that is 15 centimeters This is 15 centimeters were coming as soon as you liquid so full of it, he can see it till here Because the rarer to denser shift towards the If we are able to have normal then I I make it like this Son, something Okay, see if it's not to the scale. But yes it will help you a little bit. Children, now just look at it, it's okay, yes or no. You tell me the answer, friend, this 15 cm is for us Its radius was 15, so this one's length is also 15 cm, so this length is also 15 cm If I can say it, friend, this one is 45 degree done This must be your total length, 30. centimeter And this length of yours is 15 centimeters. So I can come up with this angle if I'll apply Snell's Law here. If I apply Snell's law, the air above is 1 In size 45 is equal to m in size a Yes or no all the children give thumbs up yes or No, can you say that this is Sir, how did the light that was coming at 45° come? 15 this 15 this radius and this height because this The height was 45 15 15 15 so 15 and 15 so May this angle of incidence at 45 degrees be yours. and angle of refracted light If it is going all the way to the bottom then it is your If the light comes then 15 or 30 or very good love you Son, this will come to you like 45 and equal to I tell you I want it sir, how did I remove it from this If you look at the triangle If you see, this 90 degree is yours, this is yours 15 this is your 30 so you can do it from Pythagoras theorem You can find here square of 30 and square of 15 You can do this by doing square and sign is perpendicular over hypotenuse so this Yours will come in 15 divided by under route of Square and 15 of square okay from here you get the value of m You will get it and how much value of M are you getting? Let's check it once, okay? value hey it's coming 1.58 okay this will give you 1.58 answer which He said this is 100 So you will get the value of n from here. 158 Clear that all the children pay attention to you Understand that he said that whatever is refractive index is that in ba 100 when you add this If you solve it then this is 1.58 and if you talk about n then son 158 Answers to You It will come, okay 158 your answer will come here o 28 students collectively gave the correct answer Gave It is very good but so many people are replying I didn't type it wrong did I? Yes, I have only 158. I wrote this because so many people were giving 158 Why not He We have lost 800 children. Oho oh some children have written 1.58 oh this Caught okay The next question is in integer type. Think 90 Seconds Will Be More Than Enough For u okay let's go Brother, yes, I put 128. There was a typing error Yes, next question, all the children, these are such questions to you. A light ray enters a solid Glass Sphere Your One Solid Glass This solid glass is fair of refractive Index is Rath thik hai at angle of idence 60 Look at the degrees, friend, whatever angle you measure They always measure with normal so this Your light is at 60 degrees somewhere. Somewhere where the rays are both reflected and written Further surface of sphere this light went to you like this And here he said that reflect also Hui And the angle between is refracted refracted and reflected Many children replied very good very Good, very good, please understand the question carefully. said that's what I made here I snails I can apply the law because I have this angle Then we know the refractive index. So you would say here 1 in sa 60 e √3 n sa aa my ater panter this is √3 bat e √3 sa The value of aaaa is coming to 30 degrees That yes, if this is 30, look friend, both are normal. So isosceles will pass through the center only The radius of the triangle formed is 30 My ater punter is degrees so this is also 30 The degree will come, right? This is a reflection of 30. You will get a degree, right? Medium on both sides. It's the same, we'll plant it again, it will reach 60 degrees, right? Yes, it is a question of 90 degrees. It happened and this is the answer It was 90 The degree is fine, I hope the children typed it correctly. did it this time Look, 90 percent child, 90 is written, very good. ok next question my enter painter okay Let's start when a light beam travels At a speed of 1.94 * 10 to the power of Velocity in Medium is giving you 1.94* Power of 10 8 The Wavelength Found in the Quds Wavelength Inn What Medium has given you is 355 nanometer so this would be 10 to the power - 9 The Wavelength of Light in the Air Will Be Air How will you think about the wavelength? Yar refractive index velocity and relates to wavelength This is c/v, this is wavelength in vacuum by Wavelength In If this is the medium then just look at the wavelength in If you talk about medium then this will go lum no * v good us wavelength o Light in air is needed, okay, then this will happen. How much will it cost in this case? N Power 8 in L 355 e 10 power na mine na apan b 1.4 in 10 Power or to go calculator use will do okay so 3 3 * 355 divide by 1.94 that is 548 yes 5489 not 10 to the power of 9 so this gives you Second option answer is coming in nanometer It will be B option, yes B option is your answer. must have been Melody Clear seems to be deteriorating in rank The next question to be asked is my Enter painter okay next question my enter painter just I want to see that melody Are you alive or dead? Okay, alive first. at rank or No the ratio of refractive index of Red Light to the Blue Light Inn Air what are you saying The Ray of Refractive index sur refractive index red light Blue The light that is your color violet indigo blue Green, Aloe, Orange, Red, remember these Wavelength is not the same, this is your white light Son, this is your order of wavelength. And if you look at the refractive index is inversely proportional to Wavelength is the Cauchy relation, but understand this. As wavelength increases, refractive index decreases. Okay, there's a causal relationship, you remember? If the wavelength increases, it will decrease. This is what the question asked. Ratio of Refractive Index of Red Light to Refractive Index of Blue Light carefully brother Seeing blue light which is refractive index is more than refractive Index of Red Light to this ratio will be less than va to A option, your answer here will be A option. my enter your answer here will be very Good kids, they are absolutely thrilled now. You have two or three subjective questions then. We will go to the objective, okay, all this Children, when I solve it, I will Save Small Angle in Notes This is an approximation formula, pay attention of light and incident on palal slab of thickness Your slab is fine, the thickness of which is How much have you paid son for t and refractive index m if the angle of incidence e theta You may get this question directly if your angle of incidence e theta for small Theta short lateral displacement of the rays B You can also remember this formula directly. It should be, but right now we are driving We will take this, okay, all the children should see if This is theta small so I want the light here If the light reaches us then this You read the shift formula delta f It is the sine of a minus a divided by cos Come on, they say this happens Now here's your honesty. Chat to vote honestly How to vote I have to write, son. To vote, just write in the chat He will do whatever he wants to do or watch it. Small Angle Approximation in For Small Angles When your theta is small, then r is also small. What will be the angle of incidence if your If it is towards then the relative angle of refraction is also If it is towards zero then you will know that Whether it is about theta or tan3, you can calculate it. you can take theta and k theta's if your If that's the case, you can take her for one, son. I'll write this down as t * i - r / ba k This one will be this is Delta what should I do now, I have to calculate theta and m If you want in terms then all the children just do this. See if I can apply Snell's Law here. because I have to remove r so if I Applying Snell's Law, 1 * s theta is equal to * Small angle in theta em a r Will you talk to me honestly? How many matches have been made, this is theta minus theta by m so this will give you t * theta * I -1 Bye I sincerely son I wish you all I will ask from whom this answer came. Did you go, yes or no, son, you must write it in your notes. But tell me honestly, who has told themselves I had solved it and you said that Sir, lateral The formula for shift is this: if I have small Matched love has to be applied angle approximation You Son, because I know your problems. Why are you writing because you are busy printing notes. stuck Ho you guys are enjoying Shag Notes Write it so it will be saved later you idiot So you have to read it yourself No, you should have solved this yourself. That brother, in small angle approximation It will become one or aa minus aa is now in the question This direct formula would have been objective. So you solve it Donkey, yes, the notes are still there, friend. Notes Hey Dinkar Sir, please look at the problem. What is happening because of this, they don't even get this option. two so much More Yes, hey, you hidden person, what will you do physically? You can still sell the notes to earn money. I have taken the notes Rajvan Sir, brother give it to me for ₹1. I will give it to you, okay, they are sold out online. What will you do with the notes, you have to read them. Oh my god, he's still writing notes. Let's go brother, chhap chhap, it's fun. I am giving you a great impression, yes yes yes keep pressing press and write Go son, we call this the Brivist Law. The question has come two or three times, okay, yes. Sell ​​it, it's okay to sell it along with the note and phone. Write it down brother, monochromatic light Falls to an angle of incidence i on slab of transparent material refractive You have read this many times in the index of the material. You must have seen it, okay, we call it B Remember to be a Brivist Law, okay, your light came here at some angle. On the incident of I, he has said that what is the relation between i and m What is the difference between refractive index and aa? The relation must be true at the reflected end refracted ray r machli perpendicular so from here the light bounces your will back up and return to denser light such He has said that between them what kind of relation should there be in it that this If both are at 90 degrees then I He said, friend, if this is i, then this will also be i. If it's 90, it'll be yours. 90 - ah, yes, or No, because the linear pair is equal to 180. If you want then 90 this is so this is i so this is 90 - Come on, I can apply Snell's Law to this I have to star mark the question many times. It has arrived, okay, so this will be yours for 1 * sa i is equal to u * sin90 - i son then sin's angle this is what you call i Brivist Remember the angle, never come directly by name If we go, there is polarization in the topic, yes very good wish son okay t i = u okay so Brightest angle is your polarization In the topic of when your light is like this Reflects and reflects If the angle between them is 90 degrees then Your light is partially polarized. Partially Polarized and This is Fully Polarized light becomes your own remains perpendicular to the plane, okay this Angle we used to call Brivist as Angle yes Son was revising the topic of polarized light. So, you have got this question many times. Next this is NCERT based question And you can also find this in your PY cues. It will go well You will also find it in your PVA kit. I think I put this in homework. What did you not keep, come on, no one will give you his All the children will also be found in Peeva Ky This is important, write it down but remember it. keep topic what is this called area of luminance okay what do you call this Beta Area of luminance okay many people have read a Point Source of Light Is Placed Directly Below the surface of the lake at a distance h From the Source Find the Area on the Water from which the light will come out from the Water is the area of ​​Illuminati power. The question hasn't come yet, but let's go. First let's talk about area of ​​illuminance Power has the concept of solid angle Half the children will do brain work, no one will do it now Look at this, suppose its refractive index index im and here is your Air you can connect a bulb or a point source placed here which H Distance H Distance Below Yes, let me tell you whatever light is there, son. You must have gone here, that is a normal incident. Whatever light you have here will go off like this You must have gone to dance to rer, you know sir away From the normal, it will become a particular This is where the critical point will be. It must be hitting at an angle and the light will go like this doing I will have all the children, yes or no. Tell me whatever light may have gone off beyond this So TR must have done it because the angle of Incidence will be greater than critical angle So sir, what I mean to say that the light will turn on is that a region somewhere on your surface This will happen A region somewhere on your surface From which light is coming out will it be yes or no Yes very good, so this circle is like There is a bulb, light will come out of it. It will go off the surface It will go off the surface Will it go away from the surface? You understand who the type will be. from which the light can go out Yes or no, yes very good, this is what you call a circle. Are your area off? luminance this circle you call your area of ​​luminance so your area of ​​this Question on finding radius and area All the children may be here, just look here. Now let me question this numerically. Your source was son, this was your H depth Whatever you have going on here is critical. She was creating conditions, this is how this happened. Isn't it air, this is medium, I accept it. So you know the value of san theta c So sir it is va baam I said ok so this This also happened, alternate opposite all the children Making a heart on this matter sir if you like radius If you want it then put theta c then this will happen Perpendicular Over Base So perpendicular a base a to n th c o Very good It will go okay so sir how to take it out from theta If you are able to understand sine theta then right? Why not take out theta? canta perpendicular over If hypos comes here then what will come of your theta A divide by under route in m square My radius is the radius of area of Luminance is the radius through which the light is emanating. The area from which the light is coming What is radius? If someone asks you How much area will you get? If you do it, as soon as you square it, you will get Pi A. Sk divide ba m sk myve all my children Tell him that he has kept all the things intact. How deep is it and what liquid is it in? I am here, it's gone Make up your mind all the children, yes these are your notes If it should be in then you will get area of ​​luminance You can ask Radius and Jin Children learnt the concept of solid angles. If so, how much power is effective? Okay, so you need to remove it from a solid angle. He will have to leave it, many children will trouble him unnecessarily. Will do it clear very Good So this was your area of ​​luminance next. Question brother, death comes in this every time to explain In this I will give you all the information like 90 seconds or 120 seconds. I'll give you a second because it takes me a while to explain. This will take time because there are many children involved. Let's drink blood, let's go, a beam of white light Wherever you find white light, understand Violet Indigo Blue Green Yellow Orange Red This is Incident on a Glass Air Interface: This is glass, this is air, to say that. Green Light Just Suffers Total Internal Reflection: Do you understand what it means? He said that it is a green light, that is just Safars means this angle is this critical angle of Green This is the critical angle of Green Send it to the critical angle of green so that Light just made its TI R's condition The Color of Light Which Will Come Out to the Air All these parrots sitting here are repeating things. Which color comes out It will come, okay brother, till JE Advance, this You will get a lot of type questions, be careful Understand that a serious child Son, pay attention to what he said. Listen to me send the white light from here. Violet Indigo Blue Green Yellow Orange Red yeay you sent it, he said that not here Okay, here your green light is like this going Only the green light is going like this So it means Green has a critical condition. So this is theta of Understanding Green All children full concentration With such questions you will get a lot Did you know this, Violet? Indigo Blue Green Yellow Orange Red The order of wavelength is So if the order of wavelength is this then The fear of the refractive index is what happened and the sign theta si e equal to ba m y vice versa The order of the critical angle is Happened yes now I understand that I have come to know that all the colors all Colors' angle of incidence which is TE Critical Angle of Green The angle of incidence of all the colours The green one is the critical angle, so I assume Let's take Green's angle as 45 degrees. For Example: Just take a value such that It is easy because at the end I have Coming to this, we have to explain it through values ​​only. If you have to explain it, then So, okay, can you understand this? The critical angle of yellow, orange, red is So more than green This could mean that their critical angle It will be more than 45 degrees. I take 50 60 70 For example, just look at yellow, orange and red. Angle of Incidence for Yellow Orange Red What is the critical angle of 45 degrees? What were 50, 60, 70 as examples? Do you understand the angle of incidence? This is a less than critical angle in this to that means No TR If there is no TRI for them What will you get from here? Yellow exit Orange will come and Red these Understanding Violet, Indigo and Blue If the critical angle is less than 45 then I assume I take 40 30 and 20 All the children make hearts about Violet The angle of incidence of indigo blue How much did you give? 45 because of green. The angle of which was the critical angle was the same for them It was 45 if I believe it. Also 45 degrees for violet indigo blue The angle of incidence is their critical The angle is yours 20 30 40 friend, you see the angle of incidence is greater than critical angle then t will be Son, if TR happens then violet here Indigo Blue So You Will Find Green Inside You will find yellow, orange, red outside here. When we met, he asked which one The color will come out that will be yellow orange Red Third Option That Is Going to Be Your Answer yes or no option will be your answer. Hey, it's about the poll, Veere, no one has come. No, we Poles also cheat in the same way from time to time. giving as you give it's yours This is an advanced question, it is an easy question. Look carefully, such questions will help you in JEE Mains. A light beam is traveling From Region One to Region Four Tooth and Four Okay, I'll give you the poll again. Initiative Index e the region toth 4 r n n batu n Ba 6 N Ba 8 Do you understand If the refractive index is decreasing It is denser We have it rarer As the refractive index decreases So we have dancers going to rar What has he said about the angle of incidence? Theta for f the beam just misses entering region Four so I angle here what theta lu that If the light cannot enter the Just Four one, then this So denser to rarer going to the condition of the t If I can tell you, please solve this. Let's understand this is your Region One. No reason to have n0 ba 2 I think ba 2 6 8 n0 ba 2 n0 ba 6 and n0 ba 8 all children zara Look, he said this that what is here Your light is coming from this angle what theta Be that we have denser to rarer away from The Normal Dense to Rare Away From the Normally it should be like this that you just miss it Let's make up our mind about this, do you think so? Sir, did you understand the concept of just missing? that this is critically going to us here After this, Y TIR should be with us. The concept of missing is that it just I am grazing, I cannot enter inside it. I am getting it, yes very good, I love you son, my friend. Snails Law could be imposed in this place. If it is 90 degrees then there will be refraction everywhere. Snell's Law has been applied here, here, and here If you take it then n0 is not theta e equal to we get this We have n0 ba 2 in sa r The same will happen here also n na ba 6 in sa r1 then n na ba 8 na sa off 90 very good very good we wanted that So I equate these two. Son to n and n gaya sa 9v to th e sign Evers of 1/8 So what option do we have? Second option son, your answer is coming here. OK Hey, let's go now Poll ok very good and last question what we have okay last question is this Your question also came in advance. Okay, this type of question will be helpful for you. Easy and medium can be found in mains Category A light rate traveling in a glass Medium is Incident on Glass Air The interface is fine, but I think Initiative In a Glass Medium Light Ray is going Incident on a Glass Air interface of glass and air Angle of incidence of the reflected ray and Transmitted Refracted Ray Transmitted Refracted ray intensity both a function of theta r Plotted yes, there will be a mistake here, be careful Read the graph, friend. See if we have any angle of If there is an incidence is zero then your reflection will also be and Refracting will be more increasing the refract as your angle will be at the critical angle or critical angle here I'll say theta is More than critical angle would have been TR Memory Make your fraction in TR zero and 100% reflection All the children will first give thumbs up to this. concept, do you know this when you Normal incidence was talked about on the surface. As the light goes, it gets transmitted So the majority of light was transmitted The portion also reflects as If I keep increasing the angle, we have What will happen, reflection, reflection always The number of reflections keeps increasing At a critical angle, all the light is on our Pass is reflected and transmitted This is not what your angle is saying. If it is increasing then the transmission is less. When your angle of incidence is 90 Transmission will be zero only when it reaches a degree. this is What is wrong in saying that we have We have these around 100% of our Nearby it will be less, at an angle it will be less It's done and there's nothing after that Your reflection is growing, growing is growing and after one 100% If your reflection is happening then it is somewhere Is this angle your critical angle? Third The Option That Is Going to Be Yours Answer D option: Some children are saying this What are you saying brother after the critical angle? There is also a particular angle coming up where But we have transmission refracted light The light that was coming out dimmed and Then it is decreasing further, it is not critical What is TIR after angle, total Internal reflection is donkey, human is fine All light after the critical angle No transmission remains inside The refract becomes zero, son. It is said that is refracted Sir, what did he say? It's strange. I don't know what line they made Transmission decreased but light above 100% You can never go away, so you have to remember this. That it's going above 100% here. These things are wrong anyway, third option That is going to be your answer see how many percentage Indian Hey Naruto Naruto also came to us Hey Ratwa Ray Where is our melody? Gone became James What Naruto Yes, well, this is the view leader board of this. New Poll Final Leader Board View Leader Board yes this final is coming naruto in this lived How is Melody Rank Up doing? That's for sure. This was the last time I could have done something about this queen. It must be that Nitin Kumar has left his brother behind. Melody It's okay Melody beta don't give up Now the next set is coming, Usam ha Vaava Pandey also Arihant has come, look brother, this is what comes to mind The names will remain, okay, I mean the names of the top th Okay, so Melody is winning. We will have some other punters as well. Whose answers are five to four correct in Lappa Baazi Answer Four correct answers Then the correct answer will be two zero ones Many T correct answer to two ones with many It is the same ones Father-in-law, brother, I am enjoying it. Our leader board Pass Melody I'm feeling it, yes, Melody. Melody yes son Melody son look now In future, we will be in this by next year If you keep the video also then whoever wins will will be called on video y p y p ok You are doing well, you have three children Nitin. Kumar Melody and Eva Pandey Let's See Which of these will still be here after the next set? Survives in the top three Yes, the next set we get is Prim's, okay? Yes, we have some questions on this as well. what will we do right It's time to eat Hey, I need a brake, my medicine brake, prime brake Prim If you won't come back, it's okay for me. Anyway, it is to see that our good children So how far do the topper kids reach? We'll give it a break here, okay? Dinner break and then the children say dinner. It is not even ready, why don't you eat it, eat our leftovers It will taste better and it is of 4 free funds. give a break yes it's ok I'll give you a 20 minute break now. Till Na 10 PM, okay, after this our topic remains. Yes, Bhag's opinion is right, we have it Later we will do Prism Spherical Surface Plane Surface is fine n thin If the lens is fine then the last topic is the most It is more important what can be done now Brothers, whoever you are, this chapter is like this This is a colorful chapter, going to the end it is so much It becomes important as long as you run away So I grew old after reading Reflection. The thin lens part is missed every time Just wait for a while, that's all I'll say. I don't feel like giving a break because The child runs away again Go brother, eat and drink and come back, yes come come come Hello hello hello voice Hello Hello Hello, yes, where have you gone, I have run away, it's done, ta fish Yes Yes, where did you go brother, Inter Buntas, come today, right now three It's a minute, it's three minutes Yes, yes, I know, I know, I am not teaching. I am not teaching, don't worry, it's okay. You may or may not want to read them Read it, our hunter is a punter, my friend, it is amazing. We are our next punter, please tell us something, brother. tell Yes, their love is also from the basics. BA Double Sc and don't even want to study, oh where? I am not even going to read There is a big problem brother, my status is big Difficulty Yes Yes, come, come, brother, I am coming, I am coming now Some people are still eating and drinking. Eat. Eat, eat, eat slowly, okay yes So the topper we had was Nitin, right? Name was Nitin Nitin or was his name yes Nitin was there, Melody was there and Eva Panda was there, okay Yes, everything is going well Tight case ok yes optical The instruments will be separate brother, yes this The chapter is already so long, then later The same thing happens, two slaps to the last one. Hit or five, the last is the last, understand something It would not have been coming, read it separately, okay Today we will talk about thin lenses. I will do it sir, can the NEET students see it brother? what do you Explain how you will crack NEET when You don't know what to look for Eyes are needed, retina is needed Optic nerve is needed, skull is needed It happens that at least I am expecting that You might be having less things, yes right then If you have all these things, then look It must be a matter of intent now. If you want to see, then see; if you don't want to see, then see So what can I do now with the skull? like virtual reality in front It is not pasted, want to see, don't see don't See it is No yes yes yes I am very much fluent in English but the only thing is I don't want to work in English wala yes so generally once they ask me sir are you Are you comfortable in teaching English? He is saying that I am not able to understand, so I would say oh This Guy Can Only Speak in Hindi and Can not even right in hindi thoda bahut kaam kar If possible, then teach it like this and then you will understand. When work was given in the company, a little It is necessary to steal work also, okay a lot A great man had said that whenever the company If there is a salary increment of January February is in March, I said yes. If it had happened, it would have happened at this time, why would you ever think about it? Yes, I said no, you also tell me this much If you are wise then you would say eat Rewadi in winter. I said it's fun, it's just like that If you get sweets in increment then only that person Time is given in the summer just like humans If the increment is made due to heat If it is not done properly, you will get angry or cold. I get Rabi and all this, yes I said Very true, you must be getting Rewadi and that. We would eat the whole Gajak. Yes, Rewadi is given at your place. It must be fine if we get Gajjak here. yes come come come yes come brother I have come Where have you all gone? Yes, they are coming, coming, joining joining together Oh yes, there is one extra minute, brother! Many of our enter painters went there. Brother, you would remain like glue sticks to the plate on the plate Yes, let's go brother, yes we are moving ahead. started What will he do with our salary? Tell me what will you do with my salary? Just now you were asking NEET questions, then now you Asking about salary Son, you will get NEET, not NEET rank. It will look fine, leave it completely flat. paper neat yes come Brother, they have a bigger salary than others. The interest is in how much the other person is earning. How much, hey, you work hard on yourself, friend. Yes, yes, this is included in the salary brother. C is written This gave them a salary Yes, yes, when they get their salary cheque Otherwise they will say Sir, here is your cheque, then many I will be worried for days, friend, the money has not come. If the money hasn't arrived, they will say we gave you a cheque. We didn't even give the one with the cue, we wrote a check. Just go son, you will get some like this. Improve your English, okay, yes in salary written C Yes, you will get it, you will get it well yes come come come Yes, yes, let's start brother. Yes, the problem with our generation is that He doesn't talk below crores, okay? They get it directly at home 00 00 more than 00 months, say 000 months, after that He has not even heard lakhs. In the middle comes straight crores, yes how much If you want a job, then it's nothing, sir. Yes, how much is there in your pocket sir, it is in your pocket right now Not only this, there is talk of crores directly. In our generation, yes, if they also get jobs If you want it, you want it in crores, come here. Come on, let's go Brother, come, come, come Now let's go and do the next part about to start okay that is Prism Spherical Surface and Plane is ok After this, once the last detected detection Last Last Detection Test There is a test, it will be checked by slapping. You are alive, there is still a topic left, so if I felt that brother, the children were more in the end. If it is being made then before it is made, first we thin I will also get the lenses done and if I feel otherwise If you are alive then a break is possible here Well if it doesn't happen I feel like I'm dying If yes, then we will get it done at the same time along with other Give us a wise break and we will fix it further. So let's go brother, first of all let's look at the prism okay yeah yeah Now all the children be serious, yes hashtag Keep running what you do from the start Brother, please understand carefully the prism we have what okay prism if you Let's talk about prism, okay, if you want to talk about it. If you do, it's a refracting medium. okay this is a refracting medium listen carefully okay this is a Refracting medium bounded by two polygons bounded by two polygons inside it Polygons are ok end rectangle matte surface ok Rectangle Matte Surface Listen Attentively Son Now all the children are okay to be serious. Rectangle Matte Surface Sir Matte Surface What There are surfaces about which you It is getting refracted, you can make it matte Surface says in our syllabus if you Look at Polygon if you want to take it. you took a triangle okay you What did you do, take two triangles here? You took the polygons and joined them. Rectangle Matte Surface Makes It Your Bun Prism this is called try Hadrons Prism okay this is called tri hadron Prism is fine if you want to keep your Polygon Do you want a square or a rectangle? If you want to do it then that is also possible Well, that is also possible you have Polygons took this and then this is yours Rectangle Matt Surface Ho Gaye Beta So This Is Rectangle Prism Rectangle which you also call slab Prism, you can also call it your slab The thing is, Sir, we have more than this. If we go then we are having so much fun. ok so penta hedal prism is also yours It happens but it is not in our syllabus. ok so yours is something like this fine than this is your penta hedal prism okay So we have these prisms called penta Hadron prism so pay attention here Understand your polygons live in your The polygons remain and the rest are your rectangles. Matte surfaces reflect whatever light you It is refracting in matte surfaces The light will fall on this surface and from this surface If these two matte surfaces are removed, then our passes are being used, okay this is what Both sides have surfaces that are your mat Surface The one below is also matte but whatever Your reflection is refracted against a matte surface. It is about everything, now the first thing that comes to mind is The thing we have to keep in mind is that is called Angle of prism confuses many children Yes sir, there are three angles in a prism. Which of these angles should we take? So angle between two mat surface angle between Two Matt Surface you'll be talking about those two matte surfaces About What Refract Is Talking About which refracts what we have I am talking about what refract is being be careful Listen, if I suppose that whatever I have The light is coming, it came here, then went here, then If it goes this way then this is your angle of prism It is said that this angle has nothing to do with No, if suppose the light comes towards me She went here, she went here, so both of them are on the surface. Let the angle between the two be your angle of incidence. that the light came to me from here like this and like this If it goes away then whatever you have of these two surfaces intersection will be this will be your angle of Prism, all the children should give thumbs up and say that You understood that the light came towards you and went here. Then if she went here then this is your angle Hoga this is your angle of pressure sare Children indicate light by giving a thumbs up once Suppose we came here and then went here Then if it went here then the middle of these two surfaces The angle of prism is your angle of light. Look sir, she came here, went here and then went here again. So the angle between these two surfaces is Off prism is clear What Do Surfaces Very Good What Do Surfaces we have are being used In refresh if you extend them or Then there is no need to extend it even if that the angle between those two surfaces We have angle of prism very good now When it comes to trihedrons in our syllabus It is a prism and can also be equilateral. It could be a small angle, whatever it is. All the children should pay attention to the process of this thing. Keep this in mind because in the question of prism Little things matter a lot and I think there have been a lot of questions. We have light coming onto a surface here. This is your angle of incidence i so this is its refractive index m so All the children tell me whenever the lights are here will it go from rarer to denser, yes or no Towards normal the light will shift I had to go somewhere here, this is the direction of light but it is towards the Normal shifts somewhere near us It will happen yes or no, all children please focus. Keep it son, please keep your focus here, okay yes We'll have it right here for you r1 yes very good now light on other surface If it goes and hits us, it hits us. Pass came normal son is fine and whenever the light Dancer too rare goes, go here if you want This shift away from the normal will happen. This is your angle of emergence e then these others When it reaches the surface, this is your angle r2 between these two surfaces we have This is your angle of emergence angle of Prism a son all the children it's my Request: If you are here then at least Manage your time properly for 10-12 days You have some left, then God bless you He also gives results only after seeing your hard work. Then you should not cry at the end, my friend. I had the chance and then I did not do it, sir. What can I do, there is nothing in it Neither the teacher will do it nor will some parents be able to do it. Okay, you have to do it at the end, so if If you look at the world here, you don't want to read it. you can go okay at least you can If you are doing something wrong, do it right. Okay, here's this middle part for me. I don't understand and then I am in these middle ones I am not even able to explain to the children of my share. I know how to actually live life Your attitude is always like this if you If you are here then with full concentration It is okay to see all the important points And what I am asking for, son, please have to take care of that okay initial Direction was this in Light Actually if you Look, she is going this way, this is your emergency So this is your angle, son, this is Your angle of deviation Delta Clear now allows you to make notes in it First, let's look at some points here. But your Snells Law can be applied Here's where your Snell's Law can be applied So what are the most important points? The first important point if you look at it is that You can apply Snell's Law: One * Sa = M * You can put sa r1 at the second point We can also apply Sir Snell's law * sin2 = 1 * sa e these are the two equations we have so your Snell's Law is done, stop now son. Do not enter the two equations in the notes right now. You can put L here anytime. Are you clear about the law? If you look at it, this one is normal. This one is at 90 degrees, a normal 90 degrees. But then your A plus this one if angle I will say that, understand carefully angle A plus angle o Summation of both is the third important point Yours is angle A plus angle O, this is with us. 180 degrees happens okay and if you Point r1 p aa2 p angle o in triangle You do a 180 degree turn when you are both If we equate these two accordingly, then a The value of r1 will always come to you as r2 Look carefully at the angle of incidence. No give and take here Any angle of incidence you may have Therefore, the value of r1/a2 is always equal to A. Next remains with us equally Important point fourth we have Important points which cause deviation in light Created by a prism that bends light If you talk about deviation then You can solve this question using the exterior angle property. Let's put it this way, this angle of it and If its summation comes then see that this angle is i This whole angle will be i, this is i - r1, this is e - r2 so if you talk about delta then i - r1 + e - r2 The important formula comes i + e may a This is your fourth important thing to us The point is clear, this is the fourth one we have We would have had an important point here. So, at what angle does the prism bend the light? Bend it if you want to remove it, then angle it off. Incidence plus angle of emergence minus Whatever prism angle we have All the children are taken out and now they write notes. Here are the first important points: You should know this first, okay? Important points that you should know It should be clear, very good, love you son Next is minimum deviation and maximum When is the deviation of a prism minimum? If there is deviation, what about it? You should know the conditions of the graph So we'll talk right now, all the kids. First, let's look at the conditions for minimum deviation. I write okay condition for minimum Deviation For Delta Minimum I know many of you remember the children. The first condition is that if the angle of incidence is equal to angle of emergence where deviation is minimum and when the deviation is your minimum Son, remember the value of delta mean will come 2i - a This remains yours Next if your i and e become equal son if your aa and e become equal then and r2 will be equal Keep in mind the next important condition is r1 = aa2 and this is equal to a but your This is where it happens. Come on, yes, thin prism. are you sir what is the meaning of delta Delta is the representation of this is the Representation of Deviation How much has the light bent from its original position? This is called deviation from the direction Ta is representation of deviation okay that The light should have gone here, look carefully The light should have gone here, this is your Initial Direction of aa and light went where is this Is Your Emergent Re to kitna angle bend ho gaya that is your Deviation angle clear very good so our This condition comes if you are here Observe Snell's Law, this is the one We have a mansa here and it will come okay. If you look here, there is 1 * sa here Okay 1 * sa aa this will happen son okay so If you look here, the Snell's Law I am 1* Come, we have the same quality as you Here we can write a instead of r. and if you find the value of i then Sea of ​​Delta min + a / 2 divided by sa of a / 2 All the children should make up their mind once that you Remember that is equal to minimum deviation. On the condition of you refractive index of the If you were to extract the slab prism, then this Conditions remain with us and these conditions If you notice, the prism that is Is Light comes to us symmetrically goes symmetrically okay so this comes Reflect refracted ray parallel to base All children make a heart once Parallel to base we have yes and no Make up your mind once, son, as many children as you can I know there are survivors here, so I was not giving breaks because some children What happens is that you just find an excuse to leave. And with as bad an intention as I I want some children to learn That's why I hesitate to give a break. I was you can see okay let's go someone No, now the child who studies When the selection happens then those children They see other's stories and say, friend. How did this child do this? This child did the same content. My son has passed out from school with the same hard work. He has done it and left with the teacher but only that The thing is, you and your competition There is a difference between the person who is studying with you. The difference in that is your rank behind. doing nothing else input all of Same, okay now you think that teacher Is there something special about me that makes you There should be improvement, it does not happen. Understand this thing to a certain level, teacher. impacts how much input you then Everything is falling on it And you never see your competition. Brother, he is working so hard. what is he doing how is he maintaining focus You only care about yourself and then when If you don't get your marks, you would have come back. They are on the teacher, what did the teacher do? I did not do it, due to which I did not get my marks. Understand that this thing should be input to all students in the same way. After that the child is getting that content what is he doing with if he can justify working hard with that content So you will be behind that same content You work hard and you are ahead of many people. It will go away, it is a simple matter, it seems bitter. It will happen but the reality is that you are ahead of your competition. I am not able to understand this for the last 10-12 days. even before okay let's go no one if I Draw its deviation graph carefully. If you understand it correctly then remember your deviation The graph of angle of incidence versus angle of incidence is So these are what some kids call parabolic graphs. No brother, we have this para bidi There is no graph, okay, we have this. One Complexity graph This is the uneven graph we have. Anywhere in the Don't say it has no name Amitril We have this graph, if you look at it When angle of incidence is equal to angle of When there is an emergence, its deviation is minimum. comes that is equal to 2i - a Do you remember my entry button? Deviation maximum at a particular angle What is the angle of incidence? All the children are very good Arihant Jain I I think I read your name there too. You are answering correctly, very good son. When your angle of incidence is equal to pa Many children go to school with minimum deviation. We don't even talk about the maximum when Angle of incidence is equal to pa ba den
