Question

In Fig. 7.3, MM, is a plane reflecting surface
(say, a plane mirror) kept ((((###perpendicular to the
plane of paper.)))))#####. A light ray is incident in the
direction AO at the point 0 on mirror. It is
reflected along the direction OB. Thus, AO is the
incident ray, O is the point of incidence and OR
is the reflected ray.
