Question

A light ray strikes a mirror and retraces its path. What is the angle of incidence and angle of reflection ?

Answer

For a ray incident normally on a plane mirror, the angle of incidence is i = 0°, therefore the angle of reflection r = 0°. Thus, a ray of light incident normally on a mirror is reflected along the same path.
