[00:00:12]I don't know.

[00:00:16]>> [clears throat] >> Okay, got you.

[00:00:56]Okay.

[00:01:02]What's up?

[00:01:08]>> [clears throat] >> Are you something that you know and someone Malik?

[00:01:35]I'm going to go already.

[00:01:40]video Get you a good topic.

[00:01:46]playing mirror topic [clears throat] elaborate >> [clears throat] >> I will do short cut Sorry Google Rudraksh Okay Never I will go to the bar Optics Ray optics wave optics Wave optics start I'm already Optics sorry sorry Ray optics sorry sorry I'm a fast Body bar [clears throat] Three in the point Fast point Light Is Always Travels In a Straight line More Concept Class room I'm taking Light But it was my source Source The light Direction And the straight line Light So what Straight line level I would have You have no Google More note I like it Off video I'm going I can do I can I'm going to I [clears throat] got to go I got to I got to Source Light So what I can say Straight line Fast point Second point level The path of Light Is Called as A ray The ray The mirror The mirror mathematics The mirror Initial Final The light The ray Source I don't ray is called as beam.

[00:04:12]Hello.

[00:04:16]>> [clears throat] >> Yeah.

[00:04:25]technical terms Just can somebody tell Otherwise reflection the process of sending back of light rays which fall on the polished surface of an object is called reflection.

[00:05:14]the light polished surface same medium reflection No.

[00:05:32]laws of reflection polished surface at you the light polished surface at you the source at you source incident ray incident incident incidents incident of perpendicular draw going to be Okay. Incident rate reflected rate and normal Okay.

[00:06:15]between incident rate and normal and normal and reflected angle of reflection angle of incidence and the angle of reflection incident rate incident rate normal and reflected rate all lies in a same plane incident rate reflected rate and normal the incident rate the incident rate normal reflected incident rate normal normal reflected imagine a a plane over there total plane >> I don't know.

[00:08:13]Clear.

[00:09:35]Hello.

[00:09:36]My watch out here.

[00:09:38]Hello.

[00:09:42]Hello. Hello. Hello.

[00:09:47]Yes, sir.

[00:09:52]Okay. Okay. Okay. Okay.

[00:09:56]>> [clears throat] >> Angle of incidence and angle of reflection. Angle So what Javi reflection So either condition Follow up on it.

[00:10:15]Next No.

[00:10:19]Reflecting surface of sheet I would like more.

[00:10:22]See that it will go to G.

[00:10:25]Hello.

[00:10:26]It will light see that strike collide.

[00:10:29]The air condition of going to go on the light up similar. Joe Porter still Say Porter return for you.

[00:10:34]Joe Porter still say Porter return for you. That would have made it a normal.

[00:10:38]Aida would have made it an incident rate. Aida would have made it a reflected rate. They get Aida incident rate or Aida normal.

[00:10:45]One side of the region T. That would have made it a normal. Angle of incidence zero over angle of reflection zero over. Joe Porter still say Porter for you. Aida would have made it Note point one. First note point. Hello.

[00:10:56]Second note point Hello.

[00:11:00]That would have made it a normal spherical mirror of something.

[00:11:05]A normal spherical mirror of something.

[00:11:07]Aida would have made it a center. Aida would have made center. But a light rate similar to the strike color. Incident rate.

[00:11:14]The reflect over.

[00:11:15]You can do anything over.

[00:11:17]No. Normal incident rate similar to the normal.

[00:11:21]Reflected rate Return to go. Normal of the similar similar similar What is PR rate?

[00:11:34]sphere ray center they came your line that later normal angle a angle that you want angle a bullet that you want angle that you want a reflected ray a reflected ray the what is spherical surface the moral normal data point one that what is perpendicular ray light same path that you want to go second one that what is spherical mirror data light go line that you want to center same data normal move with the light empty as the strike for light a incident ray normal key light and normal center empty as angle that you want data same angle they would have been someone that Okay.

[00:12:27]Would you like to [clears throat] move your hand?

[00:12:32]Mhm?

[00:12:34]>> [clears throat] >> How can I call?

[00:12:37]Huh?

[00:12:38]data that No, image formation. If you want to play mirror with the plane mirror kind of plane syllabus plane mirror the next topic which I want to play mirror Come on let me get out.

[00:12:56]Pass through tomorrow image formation by a plane mirror image formation by a plane mirror the mirror what a plane mirror data plane mirror a data object point object image formation by a plane mirror the bottom of this point object by object and the point point object data point object Oh.

[00:13:29]the image minimum by the way and send it right What do they call it?

[00:14:07]Yeah.

[00:14:10]object the new light light reflection the normal brain the analysis image image image the water plane image image I do what you got What do you got in class >> [clears throat] >> What you got?

[00:15:10]the water You got a lot of fun going on there.

[00:15:13]What?

[00:15:14]point object Okay.

[00:15:19]extended object by Second point is my corner.

[00:15:24]Now for extended object.

[00:15:32]>> [clears throat] >> Extended object corner that is a border object over.

[00:15:35]Empty with object edge.

[00:15:37]AB I find same condition.

[00:15:43]It is the strike corner.

[00:15:45]I like empty corner to tell the other empty the strike corner. Okay. It is my normal region.

[00:15:52]But I don't know what I should do with my job.

[00:15:54]It would be like that and I'm going to get my head but I don't know what I am going to do now.

[00:16:01]Like the dog I don't know what I am going to do now.

[00:16:05]I don't know what I am going to reflection but I don't know what I am going to do. I don't know what I am going to do now.

[00:16:11]I don't know what I am I don't know what I am going to do now.

[00:16:14]I like I don't know what I am going to do now.

[00:16:18]I don't know what I am going to do now.

[00:16:19]I don't know what I am going to do now.

[00:16:20]I don't know what I do now. I don't know what I am I don't know what I am going to do now. I don't know what I am going to do now. I don't know what I am going to do now.

[00:16:26]I don't know what I am going to do now.

[00:16:27]I don't know what I don't know what I am going to do now.

[00:16:31]I don't know what I don't know what plane mirror characteristics of you plane mirror of characteristics of you I like I don't know what I am going to do now.

[00:16:40]What a point object by empty image formation of I don't know what I am going to do now. I don't know what I am going I don't know what I am going to do now. I don't know what I am going to do now. I don't know what I I like I don't know what I am I don't know what I am going to plane mirror of characteristics I don't know what plane mirror of object of I don't know what I am going I don't know what I don't know I don't know I don't know what I am going to do now.

[00:17:01]real image virtual image I don't lateral real image virtual image I don't know what I am I don't know what I don't know what I don't know what I am I don't know I don't know what I don't know what I am going meet actually I don't know what I am going to do now.

[00:17:18]I don't know what I am going to do now.

[00:17:19]I don't know what I then a real image is formed.

[00:17:30]>> [clears throat] >> I mean you tomorrow I do like by the way for now I would like to by the way the reflection either I got I want I want you to I want you I'm going I'm going I want you I want you I want you to meet I want you to I want you I want you I want I want I want you I want I want you I want I want I want I want I want I want I want you I want you I want I want you I want you to meet I want I want you I want object I want you to meet I want you I want you I want you I want I want you I want I want you I want you object object I want plain mirror plain mirror I want object I want I want I want you >> Yes, no.

[00:19:35]>> [clears throat] >> Yes, no.

[00:19:41]What's way we going to go?

[00:19:43]Like you know.

[00:19:47]Next to do my gunner.

[00:19:49]Next to do my gunner.

[00:19:52]Real how?

[00:19:53]Virtual net. Real image to my screen net capture company. Virtual image to my screen net capture company. Nine. Three double one. Do you actually meet Gucci?

[00:20:03]Say real. Do you really have a?

[00:20:05]So what my say inverted with the hammer?

[00:20:07]As same image to my company baby. Not screen net capture company. Do you want to watch your lover? So what my erect hammer? I don't want to screen net capture company. Nine. Okay.

[00:20:18]That would [clears throat] be my last one.

[00:20:20]Next concept.

[00:20:21]Gucci. Yes, Gucci the my camera.

[00:20:23]Otherwise not sign the class running for today.

[00:20:26]Next time I'm going to lateral inversion.

[00:20:30]Lateral inversion.

[00:20:36]Lateral inversion gunner.

[00:20:38]Not a definition for this one. Gucci.

[00:20:40]When an object is placed in front of a plane mirror, then the right side of the object appears to become the left side of image.

[00:20:58]Object the right side. Image the left side of the wall. Our image the left of the right of the wall.

[00:21:04]A two more conversion the lateral inversion. So you can buy in company Gucci. ambulance ambulance ambulance mirror inversion plane image virtual virtual I'll be laterally inverted. laterally inverted >> [clears throat] [snorts] >> I'm [clears throat] going to next image plane is virtual. It can't be seen on the screen.

[00:22:06]Second, the image in a plane mirror the virtual Third the image plane is of the same size of the object. image size image size object size size image size same >> [clears throat] >> Fourth point, important. The distance the image distance from the mirror is equal to the object distance mirror image distance image distance mirror object mirror image distance plane image plane image image Hello.

[00:25:54]Okay.

[00:25:56]Clear.

[00:25:58]Talent Practice at your destiny.

[00:26:08]What's that we know him?

[00:26:18]Jaddu plain mirror at sea image your image a object image >> [clears throat] >> plain mirror at sea Jaldi 3:30 3:30 You know, I said 3:30.

[00:27:39]Yeah.

[00:27:50]What do I call my money?

[00:28:01]Clear.

[00:28:10]Okay.

[00:28:31]Find Find the distance between object and image. Find the distance between object and image [clears throat] given in the figure.

[00:29:01]45° >> [laughter] >> Okay.

[00:29:05]Cool.

[00:29:06]80 more object touch object 8 mirror 8 mirror object back to the mirror distance to 2 cm Tell me what to do what the object uh image already created object back to the image distance to do Cool down there.

[00:29:26]What I would do >> [clears throat] >> Don't give up.

[00:30:08]Don't give up.

[00:30:13]I'll be back.

[00:30:15]Jumping tomorrow.

[00:30:21]8 object touch 200 cm to the Tell me image I got to do it again.

[00:30:29]Cool.

[00:30:30]You got the object 200 cm image 100 cm again.

[00:30:35]I'm going to go back. Plain mirror mirror back to the object distance to do the key plain mirror mirror back to the image distance to do the key to get that up.

[00:30:44]Super Baba I don't know mirror distance Oh object image 5 5 cm into my object mirror the empty mirror I don't know the mirror plane mirror mirror extended extended object I don't know image object I don't know 3 cm Okay, I don't know 45° I don't know 90° 90° >> [clears throat] >> 80 cm I don't know I don't know 80 cm I don't know 45° 2 cm I don't know 90° perpendicular I don't know distance I don't know I don't know I don't know I don't know this I don't know this I don't know this I don't know 45° I don't know 45° Let it go.

[00:32:47]>> [clears throat] >> Mhm.

[00:33:14]Huh?

[00:33:25]What time is it?

[00:33:31]Huh?

[00:33:49]Yeah, point 40 here with a point 40°.

[00:33:52]It will turn to 90°.

[00:34:00]Yeah, 90 yeah, point 40. Yeah, we got a point 40.

[00:34:03]Yeah, point 40 here with a point 40 point 40 point 40.

[00:34:06]Opposite angle. It will turn to 90°.

[00:34:08]Yeah, point 40 here with a point 40. 90 point 40 here with a point 40.

[00:34:12]Would you like that?

[00:34:13]What kind of summer is it over there?

[00:34:15]A distance of 32.

[00:34:17]The weather angle The weather angle really got a lot. Yeah, 90° money I have some money about that which is the hypotenuse. The hypotenuse money did you get that? 2 cm.

[00:34:25]A angle A angle say yeah. The A bar data side data angle someone money this side is someone in the bar. Our distance data our distance will come over.

[00:34:43]x squared is equal to 2 2 x squared is equal to 2 [clears throat] x squared is equal to 2 by 2 1 Sorry, 2 x squared 2 x squared I like that you're my friend.

[00:35:01]4 by 2 2 x is root 2 root 2 root 2 It is hypotenuse and perpendicular and base.

[00:35:09]more I don't know.

[00:35:16]I don't know yet I don't know yet I don't know The perpendicular squared plus base squared is equal to hypotenuse squared. x squared x squared x squared is equal to 2 x squared 2 x squared is equal to 2 x squared x squared is equal to 2 x squared 4 2 2 4 x is equal to 2 root 2 root 2 root 2 root 2 root 2 root 2 root 2 image distance root 2 root 2 root 2 Question what I did object to image distance is equal to object to image image distance is equal to 2 root 2 Okay.

[00:35:44]2 root 2 I don't know what you mean by that.

[00:35:51]I don't know what you mean by that.

[00:35:53]I don't know what you mean by 2 root 2 I don't Sorry.

[00:35:57]I don't know what you mean by object to image distance answer 2 root 2 I don't know what you mean.

[00:36:02]What?

[00:36:08]I don't know what you mean.

[00:36:10]I don't know what you mean.

[00:36:12]I don't know what you mean by object to image distance 2 root 2 I don't know what you Yes, sir. Yes, sir. Okay.

[00:36:17]I don't know what you mean.

[00:36:19]I don't know.

[00:36:26]>> [clears throat] >> I am you like the job plain mirror height mirror mirror plain mirror minimum image mirror What a plain mirror head Here at the key of G I Here at the feet It's a A point, it's a B point, it's a C point.

[00:37:55]out of height out of height total total number H way Tell mirror mirror height Rudraksh Himalaya 10th class >> Go ahead.

[00:38:41]Huh?

[00:38:58]Thomas.

[00:38:58]Sandeep.

[00:39:05]Look at the first.

[00:39:06]>> [clears throat] >> Mirror height at the key.

[00:39:13]More heights at the key.

[00:39:15]80 more head at 80 more eye at 80 more feet at I could be I could be I could be see what I mean. I could tell more height at the key.

[00:39:27]H I could height at the key.

[00:39:31]>> [clears throat] >> H okay.

[00:39:33]I could be the only one I know. I like it. What What I really ask tomorrow.

[00:39:39]See that I could strike at you.

[00:39:41]What I mean.

[00:39:58]What I could be at you.

[00:39:59]I don't even know what the light ray has to do with the strike at you something.

[00:40:02]Strike at the light ray.

[00:40:04]Take it. Would you have any My diagram here what I could really like it or do you like Light ray at the light ray at the light ray at the light ray. But I would say I I would say normal.

[00:40:16]Look at light ray at the light There are more than the light ray at the light ray.

[00:40:23]Clear.

[00:40:27]I don't know what you want to do with me.

[00:40:42]You just sit down and tell me you're normal.

[00:40:45]I don't know normal.

[00:40:51]normal What do you want to do with the light?

[00:40:54]Light it up. That actually incident.

[00:41:00]A dash head. Head.

[00:41:20]>> [clears throat] >> What a light ray?

[00:41:39]And I'm going to see that.

[00:41:42]I'm going to aim for.

[00:41:45]I can do it.

[00:41:48]I don't know what a B dash.
