Hey Students. In this video the focus was kept on TIR, critical angle and the factors affecting TIR along with applications.
The basics of refraction are already covered in this session: ua-cam.com/users/livejSe8MTA9JFk?feature=share
Have a look if you face problems in refractive index, snells law or other basics of refraction

[@user-wu2ob5cv6g]

thank you for explaining such clearly

[@notasimp7445]

I didn't understand a nibble 🥲 even though I rewatched it 🥲

[@BYJUSClass910]

Haha..... It's alright. Have a look at the session link I've pinned in the comments. It'll help you with the basics to understand this video.
Let us know here any specific doubt you have :)

Good evening sir 😊😊

[@souvikdutta1014]

Sir please don't rush into the topic,if possible you can bring less content but please give more time in explaining.Moreover, I must say that you nicely explained in the last part of the video that the mirage

[@BYJUSClass910]

Hi Souvik. I'll definitely keep this in mind. Also I think if you watch the session I've given the link above, it'll help you to understand the portions of Critical angle, refraction, snells law better.
Let me know if you need help with something elese :)

[@souvikdutta1014]

​​​​@@BYJUSClass910Sir,I appreciate that you replied👍.Mostly I don't get replies in doubts in other channels.I am glad that Byjus considers students' comments.Thanks a lot.😀

U r always welcome.... @gungun

I don't understand critical angle and total internal reflection

Hey

[@Isha_shridhi]

Is it in cbse?

[@amitaawasthi8865]

Sir please make videos for icse students class 9

[@amitaawasthi8865]

Sir please

[@BYJUSClass910]

Sure @amit. I am trying to cover the extra topics of ICSE in a couple of videos. Have a look at the 'Videos' section, I've done a couple of videos.
Let me know if you need any specific topic

Hi sir

[@amarjeetsingh2030]

A small candle 2.5 cm in size is placed 27 cm in front of a concave mirror of radius of curvature 36 cm. At what distance from the mirror should a screen be placed in order to receive a sharp image? Describe the nature and size of the image. Also draw the ray diagram for the given situation. Sir just can u give the ray diagram I really want please sir I have found the answer but I wanted the ray diagram

[@priyankatomar9953]

Draw the principal axis.Draw the concave mirror with its principal axis. Mark the focal point (F) and the center of curvature (C).Place the object (candle) at 27 cm from the mirror.Draw the following rays from the top of the object:A ray parallel to the principal axis that reflects through the focal point (F).A ray passing through the focal point (F) that reflects parallel to the principal axis.A ray passing through the center of curvature (C) that reflects back on itself.The point where these reflected rays intersect on the principal axis is the location of the image.

[@itsarttime759]

Why vertical inversion does not take place in plane mirror

[@BYJUSClass910]

Hi Sneha. If you try and draw the ray diagram in plane mirrors. You'll easily figure out why inversion doesn't take place. Here's an image for your reference: images.app.goo.gl/VeWeH1NA448yFfMR8
