At what angle should the axes of two polaroids be placed so as to reduce the intensity of incident unpolarized light to `1//3`.

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 ?

An unpolarized light is successively throgh two polaroids, each with their transmission axis parallel. If the intensity of unpolarized light be l_(0) , then intesity of the light after emerging from second polarizer will be

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

Two crossed polarod A and B are placed in the path of a beam of unpolarized light . In between these two polaroid, a third polaroid C is placed such that its principal section is at an angle of 60^@ with that of A. What percentage of intensity of incident unpolarized light emerges from C and B ?

(a) How does an unpolarized light incident on polaroid get polarized ? Describe briefly, with the help of necessary diagram, the polarization of light by reflection from a transparent medium. (b) Two polaroids 'A' and 'B' are kept in crossed position. How should a third polaroid 'C' be placed between them so that the inlensity of polarized light transmitted by polaroid B reduces to 1//8^(th) of the intensity of unpolarized incident on A?
