State the two laws of reflection of light. Answer. The two laws of reflection are —. The angle of incidence i is equal to the angle of reflection r (i.e., ∠i = ∠r) ∠AON = ∠BON. The incident ray, the reflected ray and the normal at the point of incidence, lie in the same plane. AO, ON and OB are in one plane.

Solution D.2. When a light ray strikes a plane mirror, the light ray reflects off the mirror. Reflection involves a change in direction of the light ray. The angle of incidence is the angle between this normal line and the incident ray. The angle of reflection is the angle between this normal line and the reflected ray.
