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

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 :

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 (1)/(2) . Now another identical polarizer C is placed between A and B. The intensity beyond B is now found to be (1)/(8) . The angle between polarizer A and C is ......

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

Unpolarised light of intensity 32 W//m^(2) passes through a polariser and analyser which are at an angle of 30^(@) with respect to each other. The intensity of the light coming from analyser is

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 unpolarised light of intensity 64 Wm^(-2) passes through three polarisers such that the transmission axis of the last polariser is normal to first. If the intensity of emerging light is 6 Wm(-2),then angle between first two polariser may be
