Question

Refractive index of diamond is 2 find the velocity of light in diamond

Answer 1

Explanation:

Refraction is defined as the ratio of the speed of light in a vacuum to the speed of light in the meduiu of interest, in the case diamond ,So n=c/v,n=index, c=speed of light in diamond. 2.42=c/v so v=c/2.42 , c=3×10 ki power 8 m/sec.
