Question

H0w fast light travel in a glass of refractive index 1.5?​

Answer 1

Answer:

C is speed of light in air or vaccum . What is the speed of the light in oil, if the refractive index of glass is 1.5, and a ray of light is travelling from the glass to the oil with a refractive index of 1.33? What is the refractive index of glass material for which the speed of light in it is 1.92 x10?

Answer 2

A light can travel
$8 \times {10}^{33}$
