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

Unpolarised light of intensity I_0 is passed through a polaroid A, and intensity of light after passing polaroid A becomes I_1 . Light emerging from polaroid A is passed through another polaroid B, whose axis is inclined at an angle 60^@ with the axis of A. Intensity of light after emerging from B becomes I_2 .

An unpolarized light with intensity 2I_(0) is passed through a polaroid. The resultant intensity of the transmitted light will be

An unpolarized light with intensity 2I_(0) is passed through a polaroid. The resultant intensity of the transmitted light will be

A beam of unpolarised light of intensity I_0 is passed through a polaroid and then through another polaroid B which is oriented so that its principal plane makes an angle of 45^circ relative to that of A. The intensity of the emergent light is

Unpolarised light of intensity I is incidnet of the polaroid. What will be the intensity of light transmitted by the polaroid?

A beam of unpolarised light of intensity I_0 is passed through a polaroidA and then through another polaroid B which is oriented so that its principal plane makes an angle of 45^circ relative to that of A. The intensity of the emergent light is

A beam of unpolarised light of intensity is passed through a polaroid A and then through another polaroid B which is oriented so that its principal plane makes an angle of 45^(@) relative to that of A. The intensity of the emergent light

Two polaroids are kept with their transmission axes inclined at 30^(@) . Unpolarised light of intensity I falls on the first polaroid. Find out the intensity of light emerging from the second polaroid.
