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.

When an unpolarised light of inensity I_0 is incident on a polarizing sheet, the intensity of the light which does not get transmittted is

When an unpolarised light intensity I_0 is incident on a polarising sheet ,the intensity of the light which does not get transmitted is

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 :
