Question

The refractive index of a diamond is 2.32. what is the speed of light in diamond? Given that velocity of light in air is 3× 10^8 m/s?​

Answer 1

Answer:

1.29 x10^8

Explanation:

n=c/v

n= refractive index

c=speed of light in vacuum

v=velocity of light in the given medium

here n=2.32

         c=3 x 10^8 m/s

         v= ?

v=3 x10^8/2.32=1.29 x10^8
