Unpolarized light of intensity I is incident on a system of two polarizers, A followed by B. The intensity of emergent light is `I/2`. If a third polarizer C is placed between A and B, the intensity of emergent light is reduced to `I/3`. The angle between the polarizers A and C is `theta`. Then :

Unpolarised light of intensity I is incident on a system of two polarisers, A followed by B. The intensity of emergent light is I//2 . If a third polariser C is placed between A and B the intensity between the polarisers A and C is theta , then

Unpolarized light of intensity I passes through an ideal polarizer A. Another identical polarizer B is placed behind A. The intensity of light beyond B is found to be (I)/(2) Now another identical polarizer C is placed between A and B. The intensity beyond B is now found to be (I)/(8) . The angle between polarizer A and C is :

When an unpolarized light of intensity I_0 is incident on a polarizing sheet, the intensity of the light which dows not get transmitted is

When an unpolarized light of intensity I_(0) is incident on a polarizing sheet, the intensity of the light which does not get transmitted is

Unpolarised light of intensity I is passed through a polaroid. What is the intensity of emerging polaroised light ?
