Question

What is the angle of reflection?​

Answer 1

Answer:

the angle made by a reflected ray with a perpendicular to the reflecting surface.

Explanation:

a) If the light makes an angle of 10o with the surface, it makes an angle of 80o with the normal to the surface. Thus the angle of incidence is 80o.

(b) According to the law of reflection, the angle of reflection equals the angle of incidence. So the angle of reflection (measured to the normal) is 80o.
