A transparent thin plate of a polaroid is placed on another similar plate such that the angle between their axes is `30^(@)`. The intensities of the emergent and the upolarized incident light will be in the ratio of

A clear sheet of polaroid is placed on the top of similar sheet so that their axes make an angle sin^(-1)(3/5) with each other. The ratio of intensity of the emergent light to that of unpolarised incident light is

A clear sheet of polaroid is placed on the top of similar sheet so that their axes make an angle sin^(-1)(3/5) with each other. The ratio of intensity of the emergent light to that of unpolarised incident light is

Two polaroid sheets are placed one over the other with their axes inclined to each other at 30^@ . The ratio of the intensity of the unpolarised incident light and the polarised emergent light is :

A clear sheet of polaroid is placed on top of a similar sheet so that axews make an angle of sin^(-1) (4/5) with each other. The ratio of intensity of the emergent light to that of polarised light is

A clear sheet of polaroid is placed on top of a similar sheet so that axews make an angle of sin^(-1) (4/5) with each other. The ratio of intensity of the emergent light to that of polarised light is

The angle between polariser and analyser is 30^(@) . The ratio of intensity of incident light and transmitted by the analyser is

A system is created by adjusting the five polaroids to touch each other. The polaroid rotates one by one about its axis to 60^(@) . Then intensity of emergent light emitted from the last polaroid will be the ...... part of intensity of incident light.

Two polaroids are in crossed situation and intensity of polarized light is zero. If third polaroid is placed in between such that it makes half angle with optic axis, than angle between two polaroids, then intensity of polarized light will be ....... Where I_(0) is maximum intensity of incident light.
