Answer 1

Answer:

At the point of incidence where the ray strikes the mirror, a line can be drawn perpendicular to the surface of the mirror; this line is known as a normal line. The law of reflection states that when a ray of light reflects off a surface, the angle of incidence is equal to the angle of reflection, θi = θr.
