Question

15. A ray of light is incident on a plane mirror at an angle of 60°. What is

the angle of reflection?​

Answer 1

Answer:

Since, angle of incidence = angle of reflection = 30 degrees. The incident ray will have an angle of reflection of 30 degrees (made with a surface normal to the mirror surface). The reflected ray will make an angle of 60 degrees (90 - 30 degrees) with the mirror surface.
