Question

When light arrives and leaves a reflecting surface the angle with the line perpendicular to the surface is what?

Answer 1

The angle which the light leaves or bounces off a surface is angle of reflection.

Explanation:

has two types of light rays. The incoming ray and the outgoing, or reflected, ray. The angle between the incident ray and an imaginary perpendicular line drawn to the surface of the mirror is called the angle of incidence.

Answer 2

the angle of reflection is the angle between the reflected wave and the "normal" (the perpendicular line to the reflecting surface).
