Question

In what cases does a light ray not deviate and the interface of two media

Answer 1

Answer:

When the Refractive index of both the media will be same, light ray will not deviate. Light deviates when travelling from one medium to another because of change in density of medium.

Answer 2

Explanation:

Answer: A ray of Light does not deviate at interface of two media in two cases. When incidence ray strikes normally at the point of incidence. If the refractive indices of two media are equal. I hope it will help you
