Question

What are the values of angle of incidence <i and angle of
rellection<r for normal incidence of light on a plane mirror.

​

Answer 1

When a ray of light is incident normally on a plane mirror it means that the angle of incidence is 0ₒ. From the law of reflection, we find that angle of reflection is also 0. Thus, for normal incidence on a plane mirror, angle of incidence and angle of reflection are 0ₒ​.
