उत्तर
incident ray— The ray of light falling on the surface AB is called the incident ray. In the following figure, PN is the incident ray.
Reflected ray— The incident ray bouncing back in the same medium after striking the reflecting surface is called a reflected ray. In the following figure, NQ is the reflected ray.

Angle of incidence - The angle formed between the incident ray and the normal is the angle of incidence. (PNM is the angle of incidence.)
Angle of reflection - The angle formed between the normal and the reflected ray is called angle of reflection (MNQ is the angle of reflection)
Normal - It is the line drawn perpendicular to the reflecting surface at the point of incidence. MN is normal.
