A ray of light is incident normally on a plane mirror. The angle of reflection will be
  1. $0^{\circ}$
  2. $90^{\circ}$
  3. will not be reflected
  4. $60^{\circ}$

Solution

When a ray of light incident normally on a plane mirror, then angle of incidence , $i=0^{\circ}$
Hence, angle of reflection, $r=i=0^{\circ}$.
