(b). Reflected ray: The incident ray bouncing back in the same medium after striking the reflecting surface is called a reflected ray.

(c). Angel of incidence: The angle between the incident ray and the normal is known as the angle of incidence.

(d). Angle of reflection: The angle between the reflected ray and the normal is known as the angle of reflection.

(e) Normal: The line at right angle to the mirror surface at the point of incidence is called normal.
