Question

what is the relationship between angle of incidence and angle of reflection in a plane mirror

Answer 1

Angle of incident and angle of reflection are always equal

Answer 2

In a plane mirror,the angle of incidence and angle of reflection are equal.

• The angle of incidence is the angle,created by the incident ray with the mirror surface and the angle of reflection is the angle, created by the reflected ray with the mirror surface.

• Now,for the reflection happening in a plane mirror;

Angle of incidence = Angle of reflection

• For example, if a light ray falls upon a plane mirror at an angle of 30° then the reflected light ray will also make 30° with the mirror surface.
