Question

WHY A RAY OF LIGHT INCIDENT NORMALLY AT THE SURFACE OF SEPARATION OF TWO DISTINCT MEDIA DOES NOT BEND WHEN IT ENTERS FROM ONE MEDIUM TO ANOTHER MEDIUM?​

Answer 1

Answer:

Originally Answered: how is light ray refracted if it is incident normally to the interface of two media? It will propagate in same direction as incident ray of light. ... So, all the parts of light will have a change in speed at the same time. So, there will be no bending but only change in speed of light ray.

Explanation:

hope it helps

Answer 2

Answer:

It will propagate in same direction as incident ray of light.

This can explained by wave nature of light :

When light ray strikes a surface perpendicularly, all its parts enter the medium at the same time. So, all the parts of light will have a change in speed at the same time.

So, there will be no bending but only change in speed of light ray.
