Question

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

Answer 1

Answer:

50° is the answer

Explanation:

Angle to the mirror surface =40°

Therefore, angle of incidence = 90° - 40° = 50°

According to the second law of reflection, angle of incidence is equal to the angle of reflection.

Therefore, angle of reflection = 50°
