3
of incidence. (True/False)

Reflected ray is the ray of light which falls on the mirror surface.
4
(True/False)

MCQ
An incident ray is 1
a) The point at which incident rays falls on the mirror.
4 b) The ray of light which is sent back by the mirror.
c) The ray of light which falls on the mirror surface.
d) The ray which make right angle to the mirror surface.
Assertion: The angle of incidence is always greater than the angle 1
of reflection.
5
Reason: The point at which light ray strikes the surface is called
point of incidence.
