A ray of light is incident normally on a plane mirror. The angle of reflection will be

• Correct answer
  A

  $0^{\circ}$
• B

  $90^{\circ}$
• C

  will not be reflected
• D

  $60^{\circ}$

Solution

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

Hence, the correct answer is option: 'A'.
