The angle of incidence of light ray on a plane mirror is 23°, and the angle of reflection should be 23°.
What do you mean by the angle of reflection?
The angle of reflection may be defined as the angle between a reflected ray and the normal drawn at the point of incidence to a reflecting surface.
According to the principle, the angle of incidence is equal to the angle of reflection. So, if the angle of incidence is 23°, the angle of reflection must be 23°.
Therefore, the angle of incidence of light ray on a plane mirror is 23°, and the angle of reflection should be 23°.
