Question

State the laws of refraction of light. If the speed of light in vacuum is 3X10 8 ms -1 , find
the speed of light in a medium of absolute refractive index 1.5.

Answer 1

n-refractive index

C=3×10^8

(n)m=c/v

V=3×10^8×2/3

V=2×10^8m/s

I hope this helps ( ╹▽╹ )

Answer 2

Answer:

2×10^8 m/s

Explanation:

Speed of light in medium = speed in. vacuum / Refractive index

= 3×10^8/1.5

= 2×10^8 m/s
