Question

Which among the following is true for a plane mirror?

• A. Angle of incidence is the angle between incident ray and the mirror surface.
• B. Angle of incidence is not always equal to angle of reflection.
• C. Angle of incidence is the angle between the reflected ray and the incident ray.
• D. Angle of incidence is always equal to angle of reflection.

Answer 1

The correct option is D

Angle of incidence is always equal to angle of reflection.

According to law of reflection, the angle of incidence is always equal to the angle of reflection. Also, angle of incidence is the angle between the incident ray of light and the normal to the reflecting surface.
