nicely presented.... watching from Canada so make an idea how badly they teach us here,,, was looking for great teacher from India like you

Thank you so much sir. You really don't know how much you've helped me when every other site was confusing me. Everyone needs a teacher like you❤

THANK U SO MUCH SIR ONLY BECAUSE OF THIS VEDIO I CAN UNDERSTAND THIS TOPIC VERY EASILY .
THANK U ONE AGAIN.

The bestest video i have ever watched....
I like ur videos a lot..
Plz keep uploading videos on these topics!

I AM STUDENT OF CLASS 8 THAT'S WHY IT WAS HARD CONCEPT FOR ME TO UNDERSTAND BUT U MADE IT VERY EASY .,... THANKS LOT🎉

[@ninification_official]

I'm class 7th and my teacher taught it and it was like okay it's good for me❤we need basics so we can all feel easy no matter what bestie just telling and I'm very proud of both of us cuz we are learning this way earlier than everyone does❤

Relative refractive index can be = 1 in case of glycerine and turpentine oil since they both have same refractive index..

Sir why it is c/v not v/c .because it is a natural senario that some thing x with respect to some thing y .we write some thing y always in denominator because some thing y available and consider as a base or reference

[@Cranberry_haley]

I wonder the same thing

Mirror refract things how could be lights will refract from transparent optical its impossible in different color whatever seen on crystal or similar substance that is definitely have some kind of combination from the complex system in selection and rejection, its need a very deep research on experiment for one epic civilization as well as human journey to space. 💎 ⚓ 💜

[@himu586]

Refractive index is always greater than 1 (true or false )

refractive index of glass is 1.5 right?

Sir please tell me from which app you made this

I have answered this question million times...
Believe me, I am sick of this question....
I use VideoScribe and Adobe Family softwares like Adobe Illustrator, etc...

Sir first of all I want to thank you for your great work u work is really appreciable because u are teaching so deeply .sir but my doubt is that as you told absolute refractive index>1 because light always travels from rarer mediums to denser medium but sir possibility is there that light also travel from denser medium to rarer then what will happen
