(a) When an unpolarized light of intensityI_(0) is passed through a polaroid , what is the intensity of the linearly polarized light ? Does it depend on the orintation of the polaroid ? Explain your answer.(b)A plane polarized beam of light is passed through a polaroid . Show graphically the variation of the intensity of thetransmitted light with angle of rotation of the polaroid in complete one rotation.

Answer»

Solution :(a)When an UNPOLARIZED light of intensity`I_(0)` is PASSED through a polaroid , its intensity becomes`(I_(0))/(2)`.No , it does not depend on the orientation of the polaroid as inunpolarized light ELECTRIC vectors are RANDOMLY polarized in all the directions.
(b)
