Question

Find the angle of incidence
and angle of reflection . When the angle of reflection of normal.​

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 0ₒ. Thus, for normal incidence on a plane mirror, angle of incidence and angle of reflection are 0ₒ​.

Answer 2

The angle of incidence is 0° so as the angle of reflection because these are taken with normal.
