A beam of unpolarised light is incident on a tourmaline crystal. The intensity of the emergent light is I_0 . The emergent light is incident on another tourmaline crystal. It is found that no light emerges out of the second crystal. If now, the first crystal is rotated through 45^@ , the intensity of the light emerging through the second crystal 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 :

A beam of light is passed through a polaroid and the latter is rotated with the beam of light as axis. The intensity of the emergent light varies between a maximum and a minimum. Then the light used is

A nicol prism is kept between two crossed Nicol prisms bisecting the angle between them. If I_0 is the intensity of light on first polariser, intensity of the emerging light is

An unpolarised beam of intensity I_0 is incident on a polariser and analyser placed in contact. The angle betwen the transmission axes of the polariser and analyser is theta . What is the intensity of the light emerging out of the analyser ?
