Question

A ray of light strikes a plane mirror at an angle of 40 to the mirror surface what will be the angle of reflection ?​

Answer 1

Hola!!

●It strikes at an angle making 90 - 40 i.e 50° with normal.

As per laws of reflection, angle of reflection is equal to the angle of incidence.

So, 50° is the required answer.

Hope this helps you ___!!

Answer 2

Answer:

answer is 40

Explanation:

this is because of <i=<r angle of incidence is equal to angle of refraction
