Which one of the following is the correct angle between the
incident and reflected rays when a ray of light incident
normally on a plane mirror?

A

a `180^(@)`

B

b `90^(@)`

C

c `45^(@)`

D

d `0^(@)`

Text Solution

Verified by Experts

The correct Answer is:
D
When a ray of light incident normally on a plane mirror.
The ray will revert back to its path as a result both
angle of incidence & reflection will be zero.

What is the angle of reflection, when a ray of light is incident normally on any mirror (spherical or plane)?

If the angle between incident ray and reflected ray is 120^(@) , what is the angle of incidence ?

A ray of light is incident on a plane mirror, making an angle 'q' with the surface of the mirror. Arrange the following steps in sequential order to calculate the angle between the incident light ray and the reflected light ray. (A) Draw a normal line on the plane mirror at the point of incidence of the light ray. (B) Note down the angle between the plane mirror and the incident light ray. (C) The sum of the angle of incidence and the angle between the plane mirror and the incident ray is 90^(@) .Determine the angle of incidence. (D) From the laws of reflection, the angle of incidence is equal to the angle of reflection. Then the sum of the angle of incidence and the angle of reflection gives the angle between the incident light ray and the reflected light ray.
