Question

If the speed of light in vacuum is 3x10 ^8 m/s what is the speed of light in glass of refrective index 1.5?

Answer 1

Explanation:

Your answer refer in Attachment.

The refractive index of a transparent medium is always greater then 1. It cannot be less than 1 ,

Because speed of light in any medium is always less than in vacuum ( V < C ).
