Question

9. The angle between an incident ray and the mirror is 30°. (a) What is the angle of incidence? (b) What is the angle of reflection? (c) What is the total angle turned by the ray of light ?​

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.
