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 :

Unpolarized light with intensity I_(0) is incident on combination of two polarizers as shown . The intensity of the light after passage through both the polaroids will be.

A polarized light of intensity I_(0) is passed through another polarizer whose pass axis makes an angle of 60^(@) with the pass axis of the former, What is the intensity of emergent polarized light from second polarizer?

Unpolarised light of intensity 32 Wm^(-2) passes through three polarisers such that the transmission axis of the last polariser is crossed with first. If the intensity of the emerging light is 3Wm^(-2) , the angle between the axes of the first two polarisers is

An unpolarized light of intensity I_(0) passes through three polarizers, sach that the transmission axis of last polarizer is perpendicular to that of first. If the intensity of emergent light is (3I_(0))/(32) and the angle between the transmission axis of first two polarizers is theta , then

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

Unpolarized light of intensity 32Wm^(-2) passes through three polarizers such that transmission axes of the first and second polarizer make an angle 30^@ with each other and the transmission axis of the last polarizer is crossed with that of the first . The intensity of the final emerging light will be

Explain with diagram, how plane polarized light can be produced by scattering of sunlight . An incident beam of light of intensity I_(0) is made to fall on a polaroid A. Another polaraid B is so oriented with respect to A that there is no light emerging out of B. A third polaroid C is now introduced mid-way between A and B is so oriented that its axis bisects that angle between the axes of A and B. Calculate the intensity of light transmitted by A,B and C.

In a system of two polarisers , it is found that the intensity of light from the second polarized is half from that of the first polariser .The angle between their pass axes is
