Question

How is the normal drawn in relationship to a flat reflecting surface

Answer 1

At the point of incidence where the ray strikes the mirror, a line can be drawn perpendicular to the surface of the mirror. ... The normal line divides the angle between the incident ray and the reflected ray into two equal angles. The angle between the incident ray and the normal is known as the angle of incidence.
