When a light ray is reflected repeatedly...

When a light ray is reflected repeatedly by a set of parallel plane mirrors, the intensity of the light ray decreases after some reflections. This is because of

A

Poor reflection from mirrors

B

Absorption of some amount of light by mirrors

C

Scattering of light by mirrors

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B
When a light ray is reflected by a plane mirror then some amount of light is absorbed by it. If a light ray is reflected repeatedly by the parallel plane mirrors then its intensity is decreased due to absorption of light.

When a light ray is incident normally on the surface of a plane mirror, the reflected ray deviates through an angle of ________

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.
