Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

On rotating the analyzer if the intensity of light rays coming out of it varies from maximum to zero, then the incident beam of light is ____

A	un-polarized
B	partially polarized
C	plane-polarized
D	polarized

Explanation:

Detailed explanation-1: -Malus’ law states that the intensity of plane-polarized light that passes through an analyzer varies as the square of the cosine of the angle between the plane of the polarizer and the transmission axes of the analyzer.
