An upolarised beam of intensity `2a^(2)` passes through a thin polarioid. Assuming zero absorption in the polariod, the intensity of emergent plane polarised light is

An unpolarised beam of intensity 2A^(2) passes through a thin polaroid. Assuming that no light is absorbed by the polaroid, the amplitue of the emergent beam will be

An unpolarised beam of intensity 2I^2 passes through a thin polaroid. Assuming that no light is absorbed by the polaroid, the amplitude of the emergent beam will be :

Upolarised light of intensity 32 W m^(-2) passes through three polarisers such that transmission axis of first is crossed with third. If intensity of emerging light is 2 W m^(-2) , what is the angle of transmission axis between the first two polarisers?
