angle of incidence comes from light source and reflection from mirror.

When a light ray interacts with a surface, we draw a normal line perpendicular to that surface.
The angle of incidence is the angle between a light ray and the normal when the ray hits the surface (directed towards the surface)
The angle of reflection is the angle between a light ray and the normal when the ray leaves the surface (directed away from the surface).
