Question

How do you define the term refractive index of two media in terms of speed of light through them?

Answer 1

1. Refractive index is the ratio of the speed of light in medium 1 to the speed of light in medium 2.
2. When light passes from one medium to another.
3. Thus denoted as , $\mu =\frac{speedoflightinmedium1}{speedoflightinmedium2}$
