00:00:00Sign Convention Mirror
00:00:24Sign Convention Mirror
00:00:26Now look, the lens is the same as all the formulas, the numerical also is the same.
00:00:34Sign Convention will come in a little bit, not the fun will come.
00:00:38You will learn a lot from your mind, it will be half an hour, you will learn a lot.
00:00:42This is your mirror.
00:00:45Know quickly, where will the center come?
00:00:49Center.
00:00:51How will the center come in front?
00:00:53The center will come in front.
00:00:56Which side is left, right?
00:00:57Here.
00:00:58Center.
00:00:59Where will the center come?
00:01:01In front.
00:01:03We seem to have studied 18-20 years,
00:01:07now we will see questions and doubts.
00:01:11In fact, we will ask children and study, but every year, some 15-20 things come up with a big deal.
00:01:18Today, I heard the first time, I said, where will the center be?
00:01:21The beach.
00:01:22Brother, the beach is left and right, that is important.
00:01:25So, it will be here.
00:01:26Okay?
00:01:27Now, let's look at it.
00:01:28This is the principal axis.
00:01:31This is the pole.
00:01:33And what happens in the beach?
00:01:35Focus.
00:01:36What is the front?
00:01:38This is the front.
00:01:40And this is the back.
00:01:42Whatever it is on the front, whatever it is on the front, whether U, V, F, R, everything will be negative.
00:01:57Everything will be negative.
00:02:00Like in the front.
00:02:02This is so good sign convention.
00:02:04Otherwise, the 10th, 12th, is very difficult.
00:02:07Go with light, go with light, go with light, go with light, go with light, go with light, go with light, go with light.
00:02:10There is nothing.
00:02:11This is the best.
00:02:13Whatever the front is on the front, everything is negative.
00:02:17Whatever the back is on the front, everything is positive.
00:02:20Whatever the front will be negative.
00:02:22What will happen?
00:02:23Negative.
00:02:24Start writing.
00:02:25The back is positive.
00:02:27The front will be negative.
00:02:28The back will be positive.
00:02:29See.
00:02:30There is nothing.
00:02:31No.
00:02:32No.
00:02:33No.

00:03:20No.
00:03:21No.
00:03:22No.
00:03:23So, what U will be minus 10.
00:03:27Where did the image come from?
00:03:28Back.
00:03:29So, what will be V will be plus 15.
00:03:36U will be minus 10 and V will be plus 15.
00:03:45Sometimes, how do you do it?
00:03:47Like this.
00:03:49Take a moment to remove its fear.
00:03:50Don't let it go.
00:03:51So, there is no question for the question.
00:03:54Don't let it go.
00:03:59Don't let it go.
00:04:01Is there someone?
00:04:15The voice becomesф╗Аф╣И?
00:04:17Okay, so now I will stop here, I want to do this remote, so what will happen, what will happen, what will happen, what will happen, what will happen, what will happen, what will happen, now tell me, here is the object and here is the image,
00:04:37object 40, image 20, so tell me, how much will we bring, two minus, where are the front, here is the front, and what is the back, sir, I don't know how it works, the front and back, I don't know how it works,
00:05:02the polished surface is the weak, so what do we call back, where the reflection is, what do we call front, so tell me, how much will we bring, minus 40, and how much will we bring, minus 20,

00:06:14So, the focal length of the focal length is negative and the convex length of the focal length is positive.
00:06:23This is a lot of questions.
00:06:28You have to sit in your mind.
00:06:3010-15 times say that whatever the mirror is negative,
00:06:36whatever the mirror is positive.
00:06:40Tell us.
00:06:45Let's see.
00:06:472-3 things remember.
00:06:49First, remember.
00:06:51The focal length of the focal length is negative.
00:06:54The other, the focal length of the focal length is positive.
00:06:59The formula is R by A2.
00:07:02Now, 4-5 questions.
00:07:04Let's see.
00:07:06Let's write.
00:07:09Okay.
00:07:10The formula is so easy.
00:07:12If you remember the length correctly.
00:07:15I remember the list of the formula.
00:07:18Let's see.
00:07:192-3 formula again.
00:07:20Length.
00:07:211 by V minus 1 by U.
00:07:241 by F.

00:07:43M.
00:07:44M.
00:07:45Minus.
00:07:46Minus.
00:07:47you need to change the sign. Mirror

00:08:07and M L
00:08:09minus M
00:08:10see
00:08:14once
00:08:15if you write it, if you write it, if you write it, there is no mistake.
00:08:20It is not that there will be a mistake. It is a good mistake.
00:08:23Every time you write it, it will be set in the brain.
00:08:29When do you put these? Remember the bottom?
00:08:31When the size of the object is small.
00:08:45Let's see.
00:08:49Let's see.
00:08:51Online children, tell us that the audio and video is clear.
00:09:04Tell us once. All good.
00:09:09In the first slide, there is nothing left.
00:09:12Thumbs up and tell us if everything is okay?
00:09:15Okay.
00:09:19Let's go.
00:09:23Clear?
00:09:28Let's go.
00:09:30Let's do a question.
00:09:31One, two questions will come.
00:09:33Three, four will come.
00:09:34There will be more understanding and the situation will be set.
00:09:37Today, there is a lot of homework.
00:09:39But if you understand one thing, it will be fun to do homework.
00:09:43Let's go first.
00:09:46In the given question,
00:09:48In the given question,
00:09:52calculate the position and nature of image.
00:10:10This is a very good question.
00:10:11This is a very good question.
00:10:12This is a basic question.
00:10:13But you will do the math.
00:10:14You will do the math.
00:10:15You will do the math.
00:10:16This is a very good question.
00:10:17This is a very good question.
00:10:18You will do the math.
00:10:19This is a very good question.
00:10:20This is a very good question.
00:10:21This is a basic question.
00:10:22But you will do the math.
00:10:23You will do the math.
00:10:24You will do the math.
00:10:25You will do the math.
00:10:26However,
00:10:27You will do the math.
00:10:29You will do the math.
00:10:31I am going to ask you a question about 15 minutes, there is no tension, but you will learn so many things.
00:10:40The point is that the sign convention, you have to see how many plus-minus you have to play with.
00:10:56There will be a mistake, we will learn, there is no tension. Now, let's see.
00:11:03And how many things will happen? Now, leave a pen and pencil, you have to ask.
00:11:10First of all, tell me, the object is in front of the mirror, not 27, minus 27.
00:11:23The fear of the sign is. The formula is written here.
00:11:27The point is 1.2, 23 and 43, but there are mistakes.
00:11:34It is plus-minus. So, understand it.
00:11:378 hours in mind, tell me that the target is the target.
00:11:41Plus-minus feels.
00:11:43The formula, you will remember the fact in 10 minutes.
00:11:46Plus-minus is a mistake.
00:11:48So, tell him once again,
00:11:5027, not 27 and why sir? Why? Why don't you? Why?
00:11:55Because the object is in front of the mirror.
00:11:59What is negative?
00:12:01From this position in front of the mirror.
00:12:03And then, look, if r is 36 and the focal length of the circle is r by 2.
00:12:08to, to 18
00:12:10no G sir, 18
00:12:12no
00:12:12why?
00:12:15because mirror
00:12:16on cave is
00:12:18so first
00:12:20see two pieces, you have send
00:12:22what do you have to do, you

00:16:17If you want to count all the concepts in this question?
00:16:22If you have done this question 2-3 times,
00:16:25how many things you want to count?
00:16:28You are saying that the entire question is
00:16:31the whole concept of mirror.
00:16:34Now, let's count one more.
00:16:36Let's count on the board.
00:16:38First, why do you say U negative?
00:16:41Because the object mirror was said in a sentence
00:16:46If you don't mention anything about it,
00:16:49real object.
00:16:50Real object is U.
00:16:53Second, formula F.
00:16:56Third, focal length is minus?
00:16:59Who is the mirror?
00:17:01Focal length is minus.
00:17:02Fourth, M.
00:17:04F upon F minus U.
00:17:06Fifth, M.
00:17:08What do you say?
00:17:10Real image.
00:17:12Fourth, M.
00:17:14minus V by U.
00:17:16Sattva, M.
00:17:17H upon H.
00:17:19Brother, one question.
00:17:21How many things are happening?
00:17:23Seven.
00:17:24I mean, this question is like,
00:17:26write a revision on it.
00:17:27That when we read a copy,
00:17:29this question is,
00:17:30one time, rough copy.
00:17:32This question comes from itself.
00:17:33All the questions,
00:17:35all the concepts,
00:17:36one single question.
00:17:38If the candle is moved,
00:17:53if the candle is moved,
00:17:55candle is moved towards the mirror,
00:18:14then, then, then, then, how the screen, how the screen is to be moved?
00:18:41Now, this is also a very sweet question.
00:18:46If you look from the mirror,
00:18:48listen, this is also a part of it.
00:18:50You will also have 20 minutes in this question.
00:18:53Then, what is the work?
00:18:54Look,
00:18:55how far the candle was moved?
00:18:5827.
00:19:00And where was the image?
00:19:0354.
00:19:05As a result,
00:19:06Sir,
00:19:07How many things have been done?
00:19:09Exactly.
00:19:10One thing,
00:19:11it is a big one.
00:19:12I am moving on the mobile right now.
00:19:13You are starting physics.
00:19:14One thing,
00:19:15you have created the size.
00:19:17And, inverted is also created.
00:19:19Because the image is real.
00:19:24And,
00:19:25I have given it,
00:19:26this one, this one, this one,
00:19:27this one,
00:19:28back then,
00:19:29and behind then,
00:19:30you are learning physics.
00:19:31How do you work?
00:19:32The image is inverted and enlarged.
00:19:34Where the image is made for my children, what is the screen?
00:19:40That will show you the image.
00:19:43What is the screen here?
00:19:46What is the question?
00:19:49If you take the candle to the mirror,
00:19:53remember that in the last lecture,
00:19:56when the object goes to the mirror,
00:19:59the image goes far from the mirror.
00:20:03Do you remember that?
00:20:05One question was,
00:20:06remember that this object is coming here.
00:20:10Someone would tell how the image was coming from the mirror.
00:20:13Do you remember that?
00:20:15Do you remember that?
00:20:17The object is moving towards the mirror.
00:20:20The image is moving?
00:20:22Tell where to take the screen from the mirror,
00:20:25from the mirror or from the mirror?
00:20:27The answer is,
00:20:29the screen from the mirror,
00:20:32the mirror is moving from the mirror.
00:20:37I am going to take it.
00:20:45Look.
00:20:48Some days later, why are you doing the candle?
00:20:50We are doing the candle.
00:20:51The candle will be up to focus.
00:20:53After the focus, it will go out of the way.
00:20:56The screen will not be made.
00:20:57The screen will be made of what is the real meaning of the candle?
00:21:01So, where will we do the candle?
00:21:03Up to focus.
00:21:07Put the candle in this question.
00:21:10The question of the work is.
00:21:12The question of the NCRT is.
00:21:15It is a big question.
00:21:19Today, the target is 23 questions.
00:21:21Look at home.
00:21:23And I have to send homework.
00:21:26I have to ask for 23 questions.
00:21:28I have to ask for 1.2.
00:21:29It is an easy topic.
00:21:31It is not easy.
00:21:33This is a guarantee.
00:21:35Okay.
00:21:36Okay.
00:21:37First question is okay.
00:21:38Let's see.
00:21:39Put the star on the other question.
00:21:40Now, the other question is coming.
00:21:42I am going to change the slide quickly.
00:21:44I am going to write quickly.
00:21:45Say.
00:21:46Okay.
00:21:47Next.
00:21:48Let's see.
00:21:49Let's see.
00:21:50Let's see.
00:21:51Let's see.
00:21:52Let's see.
00:21:53Let's see.
00:21:54Let's see.
00:21:55When I write on the board, then write.
00:21:57You will see.
00:21:59When I write, then I will not understand.
00:22:01What I write, then I will write.
00:22:08Let's see.
00:22:10Question number two.
00:22:12Let's see.
00:22:13Concave mirror.
00:22:14Look from the board.
00:22:15Now, let's see.
00:22:16Let's see.
00:22:17Concave mirror.
00:22:18Concave mirror.
00:22:31Okay.
00:22:32Now, see?
00:22:32ilon?
00:22:33No?
00:22:34God.
00:22:35That's nice.
00:22:36They have on the board?
00:22:38It's a bit.
00:22:38I believe, God.
00:22:38It's in 2012 or even in 2012.
00:22:40You won?
00:22:42You can hear a lot of money.
00:22:43I know this is at night.
00:22:43It's not at night.
00:22:44You've got to be in.
00:22:45Bob Wolfe.
00:22:46And you won?
00:22:46You can hear it?
00:22:47I think the invested authority thatont Woods
00:22:4815 months later
00:22:52had been under the enslavement,
00:22:53or even in 2012.
00:22:54None.

00:23:30.
00:23:40.
00:23:44.
00:23:47What is saying?
00:23:49He is saying that image is three times magnified.
00:23:53What does it mean?
00:23:55M.
00:23:57This M is three.
00:23:59Real.
00:24:01Minus.
00:24:03Look.
00:24:05Size of image.
00:24:07What does size mean?
00:24:09Magnification.
00:24:11It's five times.
00:24:13Magnification is five.
00:24:15But the image is?
00:24:17Plus five.
00:24:19Look at this.
00:24:21You have to ask.

00:25:23slide, 15 questions can be solved, so I don't know why I'm looking at it here, and we can see it,
00:25:29right? M of formula, F upon F minus U, mirror of M, minus of V M, magnification of V M, mirror
00:25:40of magnification of formulae is minus, real image is M negative, virtual image is M positive,
00:25:51so it's done, now we're not keeping value, now you're in the calculation, so it's different,
00:25:58M of formulae, F upon F minus U, F is not 20, minus 20, why? which is the case, which is the case,
00:26:09which is the case, then F is minus 20, U, U is the case, but U is the case, minus U is the case,
00:26:18unknown quantity ka sign, kabhi nahi rakti, rule to seekne padeghe yaar,
00:26:25to cricket kail raha hai, chess kail raha hai, badminton kail raha hai, rule to seekhe ga,
00:26:30bina rule ke kiasse, me to sir, kail lunga, aray kail lunga kiasse, kail nye dunga nain,
00:26:35kiyo sir, phele rule sikh kya, hati ka kitna chalta hai, gho┌Сe ki kitna hoti hai,

00:31:17f,
00:31:20where should,
00:31:24an object is placed,
00:31:28so that,
00:31:32size of image,
00:31:35is,
00:31:36one by n times,
00:31:39the,
00:31:40size of object,
00:31:44gita ha ha hi.
00:31:51Sochiye,
00:31:52yoi or achcha sawale hai,
00:31:55haas toh laga ki rakhye ies ko,
00:31:57Now, sir, what has been given, sir, I will start with you, tell me, sir.
00:32:03First of all, tell me, what is 1 by N, what is magnification, okay, sir.
00:32:10But, no, sir, sir, in the last question, let me see, sir, you had written, real, or, sir, I have read the question twice, sir.
00:32:22Sir, don't you have written it, give it a virtual.
00:32:24It's a word, convex.
00:32:30Sorry, there's no real virtual, sir, you don't have to understand it, sir, there's no one in the question.
00:32:36Convex, sir, what happens in convex, come and learn it once and see, how many red diagrams you will make, this is convex,
00:32:45Look at this, this object kept, this light came, this light came, this light came, this light came, this light came, this light came, these lights are not getting anywhere, where do I bring them, back, back, back, back.
00:33:07Look at this, what made it, image, what made it, image, now tell how image is, tell yourself, virtual or erect, diminish, then they call it rear view mirror, set it in the brain, convex mirror always, small, straight and virtual image makes a virtual image,
00:33:35one child, one child, one child, is standing in front of the mirror, and it shows its image, erect, erect and diminished, so tell yourself, which mirror is, which mirror is,
00:33:55the answer is, convex, erect and small, erect and small, erect and small, and virtual, convex mirror is, so tell yourself,
00:34:09IB got it there, work, so tell yourself, you share it, in the 2 on the 2 Release this question,
00:34:16examiner,alion, andыЛ╡, administrator has ьЭ┤ы▓Иed instruction and virtual, but in this the question, examiner less,
00:34:25this meaning, it looks like you don't want it, that you know, convex mirror is always about the virtual image with the real object,
00:34:35Now tell me the value of m.
00:34:38I will write plus 1 y n.
00:34:43Because I will tell you that I am plus 2.
00:34:45Because the mirror is convex.
00:34:48Convex mirror always makes a virtual image.
00:34:52And the virtual image of m is positive.
00:34:56Now do it.
00:34:57The place of m.
00:34:58F upon f minus u.
00:35:02Cross multiply.
00:35:041 step.
00:35:05Big up.
00:35:06When you know that your mind is in your mind.
00:35:08La-parvaii is in your mind.
00:35:101 step.
00:35:121 step.
00:35:14Big up.
00:35:18Yes, online people tell me.

00:35:23Sahil Kumar.
00:35:24Aditya Govindam.
00:35:25Abhishek Jaiswal.
00:35:26Your answer is correct.
00:35:28Rudra.
00:35:31Very correct.
00:35:32Very correct.
00:35:34Aditya, Sanskriti, Nikat, Roshan, Shivamraaz, Swami Pandya.
00:35:41For all of us,
00:35:47let us know that your family has a time table daily.
00:35:48We will know that your friends are in Whatsapp.
00:35:49We will know that your friends have a time table daily.
00:35:52What's up for us?
00:35:53Broadcasting group.
00:35:54You have a time table daily.
00:35:54I will give you a little bit.
00:35:56I will give you a little bit.
00:35:58It is very big.
00:36:00Okay.
00:36:02Let's go.
00:36:04Now, what do we say?
00:36:06What do we say?
00:36:08U of the value.
00:36:16Let's go.
00:36:18What do we say?
00:36:20Cross-multi-black.
00:36:22F
00:36:24N F
00:36:26equal
00:36:28F minus U
00:36:30If we take U here,
00:36:32then plus U,
00:36:34we take it there, minus.
00:36:36Then U will come.
00:36:38F, one minus.
00:36:52F, one minus.
00:36:54F, one minus.
00:36:56But there is no such option. Everything is correct.
00:37:00So, the thing about lens?
00:37:02What did they do?
00:37:04What did they do?
00:37:06Rearrange.
00:37:09Rearrange, remember?
00:37:12What is common?
00:37:14Minus.
00:37:15Minus is common.
00:37:16What will happen?
00:37:17N minus.
00:37:19Do you remember?
00:37:20And what was the minus sign?
00:37:23Real object.
00:37:24Answer.
00:37:25Option.
00:37:26How will it be?
00:37:28Answer.
00:37:30Option.
00:37:31F.
00:37:34N minus 1.
00:37:36This is the answer.
00:37:38Sir, what did you do here?
00:37:40I will tell you the board on the back.
00:37:43You have done it right?
00:37:45Okay.
00:37:46But there is no option.
00:37:49If it is such a thing, you will give it.
00:37:51If it is such a thing, you will give it.
00:37:52If it is not like you.
00:37:53So, what do you do?
00:37:55Minus is common.
00:37:56Minus is common.
00:37:57Now, let me tell you this.
00:37:59Is this right or is this right?
00:38:01Yes.
00:38:02The two of them are the same.
00:38:04They say, rearrange.
00:38:05This and this is mathematically the same.
00:38:08Yes.
00:38:09Yes.
00:38:10But option.
00:38:11Minus is common.
00:38:12Minus is common.
00:38:13Minus is common.
00:38:14Minus is common.
00:38:15Uh,
00:38:16Minus is common.
00:38:17you didn't say, you didn't say, you said, minus 80 plus 3, you can see, minus 80 plus 3, minus, why does not say, minus sign, only says, object's nature,
00:38:29you can see, here the answer is, minus 24, you didn't say, you didn't say, 24, you didn't say, 24, but what was the answer, but what was the right, minus sign, what was the right,
00:38:44object's nature, now, this is the right answer, this is the right answer, with minus, but this is the option, what is the answer,
00:38:57fn minus 1, then, what was the minus sign, what was the right, object is real, real object, okay, let's keep star,
00:39:07star, 1 minute here, I will wait, if there is doubt, ask me, the most important thing was, this plus sign, this plus sign, this plus sign,
00:39:22my kids, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign, this plus sign,
00:39:52Let's write the next one. I'm cutting a little bit, the question is.
00:39:57I'm cutting a little bit.
00:40:01Find out the, find out the length of the image.
00:40:15Find out the length of the image and longitudinal magnification.
00:40:33I'm cutting a little bit. Find out the length of the image and longitudinal magnification.
00:40:45You can make a diagram. If you remember something, it's bigger.
00:40:50If you know the diagram, you can see it.
00:40:53How many times mirror formula?
00:40:56How many times?
00:40:58How many times?
00:40:59How many times?
00:41:00Because it's different from each corner.
00:41:04And I think it's another thing.
00:41:06What?
00:41:07One corner is 2F.
00:41:10So, it will become 2F.
00:41:14First, make a diagram.
00:41:1615 minutes.
00:41:17This is big.
00:41:18And what is the big question?
00:41:21What is the big question?
00:41:23What is the big question?
00:41:25What is the big question?
00:41:27No step.
00:41:29We will put the whole time.
00:41:31Look at the way.
00:41:33I understand.
00:41:34The target is.
00:41:35It's a big question.
00:41:36Today, you need to make me at home work.
00:41:38I need to be at home work.
00:41:39How many times?
00:41:40How many times?
00:41:41Come on.
00:41:42All people look at the board.
00:41:43Now, leave the pen pencil.
00:41:44The pen pencil.
00:41:45Five minutes.
00:41:46I understand that.
00:41:47First, you need to elaborate a little question.
00:41:49Don't run away from the solution.
00:41:51Don't run away from the solution.
00:41:52Don't run away from the mind.
00:41:54What is the way.
00:41:55You know, sir.
00:41:56You know, sir.
00:41:57You know, sir.
00:41:58You know, sir.
00:41:59You know, sir.
00:42:00You know, sir.
00:42:01You know, sir.
00:42:02You know, sir.
00:42:03It's different.
00:42:04It's different.
00:42:05It's different.
00:42:08It's different.
00:42:10It's different.
00:42:11Where's the pen pencil?
00:42:15Let me tell you.
00:42:16Point B.
00:42:17Point B.
00:42:182F.
00:42:20It's different.
00:42:22Therefore, B.
00:42:23The pen pencil will be here.
00:42:26This will be right.
00:42:29It is a generic.
00:42:30It will become different.
00:42:31Go.
00:42:32So, here will be the journey.
00:42:36Now, one direction is how to create?
00:42:43Now, let me tell you, how to make a direction?
00:42:47One direction is how to take away?
00:42:50If you understand,
00:42:51you can think you can move it to two f.
00:42:53This means here will be the direction.
00:42:56Two f.
00:42:57This direction is so far.
00:42:594 is 4, so this is the distance. 2f minus f by 4. Feel it. If you make a bindu A's image,
00:43:11then the bindu A's distance will also be removed. So, 2f minus f by 4, 4, 2, 8, 7f by 4.
00:43:20So, tell us, A's distance. A's distance is the distance. A's distance is the distance.
00:43:257f by 4, no, it's wrong. Minus 7f by 4. What is it? Object mirror is the distance.
00:43:37Oh, there is a distance. If you sit at home, 2-3 hours, think about it.
00:43:44Plus minus ki galtiyaan hoongi. Calculation me dhikkat aayegi.
00:43:49Or, ye common hai. Ismei panic nahi hoona hai.
00:43:522 bar, 3 bar, 5 bar, galt hoote hoote hoote hoote,
00:43:56chijayain settle hoongi. Panic nahi hoona hai ismei.
00:44:01Yee tere dhimag me set hoona chahiye.
00:44:03Haan, par koi exception bhi nahi hai. Yee bhi maji baat hai.
00:44:06Agar tu eek baas chiz seek jayega, to ho gya. Object mirror ke kaha hai?
00:44:11Amne f, f, f, f nahi rukhunga. Minus f.
00:44:17Pooch kiyo? Concave hai?
00:44:20Ab laga formula. One by v, plus one by u, equal to one by f.
00:44:27Yehaan tak berabara ho. Plus aayega, ya minus aayega?
00:44:33Mirror formula mein beech mein, plus aayega.
00:44:37Disconnect to raha hai ke online ali bachche batau to?
00:44:41Ek bhaiya keha raha hai, disconnect to raha hai baakki batahe.
00:44:44Aditya Govindam, Abhe Kumar, Prashant, Pranjal, Sahil.
00:44:48Nahi. Okay.
00:44:50Thik hai. All good.
00:44:52Chalo, badiya.
00:44:57Shriyaan ne answer de diya hai four by three.
00:45:00Chalo, achi baat hai.
00:45:02Dekh toh, mujhe yaad nahi, bit answer.
00:45:09Chaliyya, ab solve karte hai v.
00:45:11U ki jaghe, minus seven f by four.
00:45:16F ki jaghe, minus f.
00:45:24Udhar jayega.
00:45:26Four by seven f.
00:45:28LCM, LCM, seven f.
00:45:32F ka, minus seven plus four.
00:45:36Minus three by seven f.
00:45:39V, minus seven f by three aayega hai.
00:45:43Have patience.
00:45:45Mujhe koji jalbaji nahi hai.
00:45:47Yeh sawal kathin hai.
00:45:50In ko dho, dho, t├нn, t├нn baad bhi kirae jai.

00:54:2915 minus or 15 plus
00:54:31one with it
00:54:32so no one will go
00:54:35M is gone
00:54:38and then M
00:54:39what will we add
00:54:41H I upon H O
00:54:43M minus 1
00:54:45H I not know
00:54:47H O 2
00:54:49so H I minus 1
00:54:52this is the same
00:54:55U minus 6
00:54:58F minus 20
00:55:01so data that is
00:55:02so M will come
00:55:04M minus 1
00:55:07right now
00:55:09now
00:55:11now
00:55:11small size
00:55:15small size
00:55:16when it happens
00:55:17when it happens
00:55:18when it comes to this rod
00:55:19not to keep it
00:55:20like this
00:55:20in height
00:55:22or small
00:55:23or small
00:55:24there is no difference
00:55:25in your mind
00:55:27the right thing
00:55:28came to your mind
00:55:29that is the next question
00:55:30M minus 1
00:55:31M minus 1
00:55:32M minus 1
00:55:34M minus 1
00:55:35If the size is like this, then we will put it.
00:55:41Now tell us, the two corners are on a different distance, but the size of the object is small, so it does not keep a different distance.
00:55:52Now what do we put?
00:55:54ML is equal to M┬▓.
00:55:57ML, length of image.
00:56:00But a length of object is equal to M┬▓.
00:56:10So, length of image is minus M┬▓ into length of object.
00:56:16Let us understand. These two questions are the same.
00:56:22This is the same.
00:56:24So that you have to sit in your mind.
00:56:26Let us sit in your mind, height, big or small, there is no difference.
00:56:34The way to handle it is the same.
00:56:36Let us see.
00:56:38There is no difference.
00:56:40It is also the same.
00:56:42It is also the same.
00:56:43Everything is the same.
00:56:45HI.
00:56:46How much?
00:56:471 mm.
00:56:48So tell us, HI will come.
00:56:50Minus 1.5 mm.
00:56:53I will sit in my mind.
00:56:56I will sit in my mind.
00:56:58I will sit in my mind.
00:57:00Sir, these two questions are the same.
00:57:02Sir, height, big or small, there is no difference, Guruji.
00:57:06It is not necessary.
00:57:07But you have written that object size is small.
00:57:09It is in my mind, Sir.
00:57:11When will it be different?
00:57:13When the rod is along the axis.
00:57:18The next question is this.
00:57:20First, do this.
00:57:22Make it a bit bigger.
00:57:23That, Sir, height, big or small, there is no tension.
00:57:27The two to do it is the same.
00:57:30Therefore, your mind is the same.
00:57:32Your mind is the same.
00:57:34Your mind is the same.
00:57:35Your mind is the same.
00:57:36Your mind is the same.
00:57:38Let us see.
00:57:39Let us see.
00:57:44Tell us.
00:57:45What is it?
00:57:47Let us see.
00:57:48Let us see.
00:57:49Let us see.
00:57:50Let us see.
00:57:51Let us see.
00:57:52Let us see.
00:57:53Let us see.
00:57:54Find out the length of image.
00:58:00If object is kept along the principal axis.
00:58:12Along.
00:58:13Along.
00:58:15Along.
00:58:16Along.
00:58:17Along.
00:58:18This is a big job.
00:58:19Look.
00:58:20This is the principal axis.
00:58:21And where is it?
00:58:23Along.
00:58:24Along.
00:58:25Like.
00:58:26What?
00:58:27I will tell you something else.
00:58:28I will tell you something else.
00:58:31One second.
00:58:32Please.
00:58:33Understand.
00:58:34Just don't click copy notes.
00:58:36This question will not come.
00:58:37My son will understand.
00:58:39This will not come.
00:58:41Concepts will come.
00:58:42This is why, I have to grow up.
00:58:44The time of 9th and 10th was different.
00:58:46From that science from the book, that was the same question.
00:58:49If you have any questions in Hindi or English, which are the questions behind the book.
00:58:54There is no such thing.
00:58:56So, don't give any questions to these notes.
00:58:59Don't think about the concept.
00:59:01I write another question here.
00:59:03Tell me what you think.
00:59:06This is 10 cm.
00:59:08And this is 40 cm.
00:59:13Now tell me.
00:59:14What will we do here?
00:59:17Here, two times.
00:59:19Here, the rod is small.
00:59:22The focal length is small.
00:59:24The long length is small.
00:59:27Here, the long length is small.
00:59:30To handle it, it won't look like it.
00:59:35ML is equal.
00:59:38No, no, no.
00:59:40How many times the mirror formula?
00:59:43How many times the mirror formula?
00:59:45Why sir?
00:59:46Have you done such a question?
00:59:48Yes.
00:59:49Look at this.
00:59:50Look at this.
00:59:51Look at this.
00:59:52Look at this.
00:59:54You will have to study one or two hours.
00:59:57Then, the things will be adjusted.
00:59:59Yes, it is easy to get in class.
01:00:01Because I am studying.
01:00:03I am driving force.
01:00:05Driving force means that I am driving in the car.
01:00:08You are sitting.
01:00:09You are sitting.
01:00:10You are sitting.
01:00:11You are good.
01:00:12Yes, yes, yes.
01:00:13Yes, yes.
01:00:14When you are sitting in the car,
01:00:15and sitting in the car,
01:00:16and sitting in the car,
01:00:17then you are driving the car.
01:00:19Then you will come to understand.
01:00:21What will you think?
01:00:22Yes, sir.
01:00:23Yes, sir.
01:00:24It is a big.
01:00:25But you have to understand this.
01:00:27Look.
01:00:28This is height.
01:00:29Is height.
01:00:30zost 2 minutes.
01:00:32Height.
01:00:33Is height big or small?
01:00:35Is there any difference?
01:00:36No.
01:00:37Do you manage that to handle.
01:00:39No.
01:00:40Do you like it?
01:00:41What is this?
01:00:42No.
01:00:43But the other student,
01:00:44is small or big?
01:00:45It does both do work?
01:00:47No.
01:00:48If the young and other students is big?
01:00:50How many times?
01:00:51No.
01:00:52If the young and other students is very small,
01:00:53then this is the formula.
01:00:56Where does this seem?
01:00:58When the size of the object is small, Guru Ji knows how it is going, it is small, 1 mm, 1 mm, data, focal length is going in centimeter, Rajkumar, focal length is in centimeter, but the size of the object is mm, so how is the size of the object?
01:01:20When the object is small, when the size of the object is small, online children, what is my voice until you reach to them, Sahil, Aditya, Govindam, D.V. Singh, very big.
01:01:45You have to sit in your mind, these are ridiculous things, today's whole class is numerical, go to home, don't take mobile, go to my email, you are going to move, you are not going to know, you are going to get a day, you are going to try and get a day, you are going to try and get a day, sir, one or two times, five minutes, ten minutes, your screen time is not going.
01:02:09I am trying to do it for myself, and I am not trying to do it for anyone.
01:02:14That sir, I don't think the whole day I don't feel mobile at all.
01:02:17There is so much work, sir, to try and remember the formula,
01:02:21Botany, Geology, NCRT study, sir.
01:02:24Where did you study mobile?
01:02:26Why did you study your life?
01:02:29It's a little bit difficult.
01:02:31Try to do mobile slowly, slowly, slowly, slowly,
01:02:34I will reduce the screen time.
01:02:36When I go through my learning process, I will write a question,
01:02:39I will write a question, I will write a rough copy.
01:02:41It will be your confidence.
01:02:43Okay, let's explain.
01:02:46Now, object size, how is it?
01:02:49It is small.
01:02:50So first, you know, you will have 60 or minus 60.
01:02:53F, 20 or minus 20?
01:02:57So first, M, go.
01:03:00F upon F minus U.
01:03:02M is minus 1
01:03:06Is it right?
01:03:08Tell us the length of image
01:03:10is equal
01:03:11length of object
01:03:14Minus
01:03:16doesn't mean it is inverted
01:03:18M minus 1
01:03:20length of object is 1 mm
01:03:22So
01:03:23minus of .25
01:03:25is the length of image
01:03:28minus of .25
01:03:29Look
01:03:31Sir
01:03:36both of them are in a different distance
01:03:39It is absolutely right
01:03:41I have accepted you
01:03:42Oh, it is a M M
01:03:44It is 60 cm
01:03:46So there is no more
01:03:49than the two corners
01:03:49So this formula is made
01:03:52Look
01:03:54When will it look at the size of the object?
01:04:00Small
01:04:00do it here, make it too, and write it for this, don't put it for this, don't put it for this,
01:04:07write it for this, there is no shame, there are your notes, as many things are written,
01:04:13there will be much benefit, tell me, ask no doubt, don't do anything, don't do anything,
01:04:24what are you thinking, what will you think, what will you think, what will you think, no matter,
01:04:29come up, ask a bell, ask a doubt, go to the evening, ask a doubt, I get out of the room, I sit down,
01:04:37I sit in the cabin, I sit in the cabin, I sit in the cabin, I think I go to the cabin,
01:04:43I feel a restriction of the child, I knock and ask, open to all, come in, ask a doubt,
01:04:52take a pulse and go, there is no doubt, but come, ask a doubt, easy to access,
01:04:59they are available to everyone, ask someone first to ask Manojjji,
01:05:03to meet with Ag sir, then knock in the cabin, then go to the cabin,
01:05:07I didn't know that, oh sir, I couldn't do so much, that's why I stopped sitting inside,
01:05:13on the sofa, be easily accessible to everyone, every child can meet,
01:05:18you can say something, you can ask a doubt, ask a bell, ask a bell,
01:05:23you are for people, and you understand this, you are, then we are, then we are,
01:05:29you are the king, you are the king, you are the king, you are the king,
01:05:33all of those who are going on, this is all you are the king, you are the king,
01:05:49we talk about the head, tell our problems,
01:05:53do the question, do the numerical,
01:05:56it will be great, everything will be good.
01:05:59Let's go, is this ok?
01:06:02The next question.
01:06:08Let's go.
01:06:11Do I go?
01:06:14The next question.
01:06:16This is another good question.
01:06:17Now, let's go.
01:06:20Find out the
01:06:27perimeter
01:06:29of
01:06:33image.
01:06:37Okay,
01:06:38he took a session on Sunday,
01:06:40but he has revised the entire lens.
01:06:43His PDF is on the telegram channel.
01:06:46He is on the electronic panel.
01:06:48Send that down.
01:06:49And write ten concepts.
01:06:50There are five 5 lectures.
01:06:53You will revise it.
01:06:54You will revise it,
01:06:55it will be revised by half hours.
01:06:56How many concepts?
01:06:58Ten.
01:06:59It's a video on YouTube. I've read it on Sunday. I've read it all. You can see PDF. You can see PDF. You can see it. You can see it. You can see it. You can see it. You can see it. You can make a short note. So, you can make a video of what kind of concept? 10.
01:07:1410 to 10. You want to see it. Then you can begin.
01:07:21Now, this question has been big.
01:07:27Please tell us how this approach is possible.
01:07:44you
01:07:48and tell me
01:07:51i am a
01:07:52a
01:07:54a
01:07:56a
01:07:58a
01:08:00a
01:08:02a
01:08:04a
01:08:06a
01:08:08a
01:08:10small or big?
01:08:11small
01:08:13Now, I will see how I can solve it in the board.
01:08:15Pen pencil, put it in the board.
01:08:17Mommy, look at it.
01:08:18Mommy, look at it in the board.
01:08:20Mommy, look at it.
01:08:22A, B and C, D.
01:08:25Tell me quickly.
01:08:27Is it height or length?
01:08:31A, B and C, D.
01:08:34What is this?
01:08:35A, B and C, D.
01:08:38What is this?
01:08:40Height.
01:08:42F upon, F minus U.
01:08:45M, F upon, F minus U.
01:08:48F minus 20.
01:08:50U, minus 60.
01:08:54Minus half.
01:08:56What is this?
01:08:57What is this?
01:08:59HI upon, M minus 1.
01:09:03HO, 1 mm.
01:09:06So, HI minus 1,5 mm.
01:09:10So, minus 0.5.
01:09:13What is this?
01:09:15What is this?
01:09:16Height.
01:09:17Now, tell us about it.
01:09:18AD and BC.
01:09:20You put it in the description.
01:09:22Put it in the description.
01:09:23Put it in the description.
01:09:25Put it in the description.
01:09:27It doesn't mean physics.
01:09:29AD and BC.
01:09:34It does not meanс║еp.
01:09:36This is long, height.
01:09:38This is long.
01:09:39It is long.
01:09:41And?
01:09:42How long?
01:09:43How long?
01:09:44How long?
01:09:46If you were small.
01:09:48Longф║Ж,
01:09:50Then?
01:09:52I'm into m.l thick.
01:09:54or length of image
01:09:57is equal to minus m square
01:10:00m value minus 1, object
01:10:05is equal to minus 1, 4
01:10:10minus is equal to minus 1, 4
01:10:12minus is equal to show to us
01:10:13how is it?
01:10:18I'm making a photo on the side
