Question

If a ray incident normally on a plane surface, what will be the angle of reflection?​

Answer 1

Answer:

When light ray is incident on plane mirror it undergoes reflection. When the light ray is incident normally on the plane mirror then by using laws of reflection angle of incidence is equal to angle of reflection. Hence, as the angle of incidence is zero degree angle of reflection is zero degree.

Answer 2

if a ray incident normally on a plane surface the angle of reflection equals to 0° . since the light bounces back after reflection
