If there is zero absorption in the polaroid and if the intensity of plant-polarized light coming out of polaroid is `A^2` , then the intensity of the incident beam will be

Two 'crossed' polaroids A and B are placed in the path of a light-beam. In between these, a third polaroid is C is placed whose polarisation axis makes an angle theta with a polarisation axis of the polaroid A. If the intensity of light emerging from the polaroid a is I_(o) then the intensity of light emerging from polaroid B will be

Two polaroid A and B are kept in crossed position. How should a third polaroid C be placed between them so that the intensity of polarized light transmitted by polaroid B reduces to (1)/(8)th of the intensity of unplarised light incident on A ?

When a polaroid is rotated the intensity of light does not vary. The incident light might be:

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.

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

Two polaroids are crossed. If one of them is rotated through 30^(@) and unpolarised light of intensity l_(0) is incident on the first polaroid, then the intensity of transmitted light will be

Two polaroids are crossed. If now one of them is rotated through 30^(@) and unpolarised light of intensity l_(0) is incident on the first polaroid, then the intensity of transmitted light will be
