Question

Refractive index of Glass is "3.2" what is the velocity of light in glass full solution plz

Answer 1

Explanation:

Refractive Index medium = Speed of light on the medium

Let the speed of light in glass = V

Thus,

3/2 =3× 10^8 / v

V = 3×10^8×2/3

V=2×10^8 m/s

Hope it helps

Answer 2

Answer:

It means that the speed of light in glass is 2/3rd the speed of light in air (or vacuum).
