Question

The refractive index of glass is 3/2 velocity of light in glass would be?​

Answer 1

Answer:

It is defined as the ratio of the speed of light in vacuum (c) to the speed of light (v) in the given medium i.e. μ=cv. If the refractive index of glass is 1.5, then μ=32=cv , where v is the velocity of light in glass. Therefore, 32=cv⇒v=2c3
