Question

what is relative refractive index how can i find the refractive index of a medium

Answer 1

hey there...

here is ur answer...


relative refractive index is the ratio of speed of the light in two different mediums.

how to find the refractive index:

we need to

divide the speed of light in vacuum by the speed light in that medium.

hope this helps!

Answer 2

Hey! here's ur answer.
The ratio of the speeds of light in a given pair of media is called the relative refractive index for a given pair of media.
You can find the refractive index by this process from the picture.
