Vedclass · Answer

(D) According to Malus's Law,the intensity of transmitted light is given by $I = I_0 \cos^2 	heta$,where $	heta$ is the angle between the transmission axis of the Polaroid and the plane of polarization of the incident light.As the Polaroid completes one full rotation ($0$ to $2\pi$),the angle $	heta$ changes continuously.The intensity $I$ becomes maximum when $	heta = 0$ and $	heta = \pi$,and it becomes zero (minimum) when $	heta = \pi/2$ and $	heta = 3\pi/2$.Therefore,the intensity of light becomes maximum twice and zero twice during one full rotation.

Plane-polarized light passes through a Polaroid. While observing through the Polaroid,it is seen that when the Polaroid completes one rotation about the direction of light,which of the following is observed?
