Two nicols are so oriented that the maximum amount of light is transmitted. To what fraction of its maximum value is the intensity of transmitted light reduced when the analyser is rotated through (i) `45^(@)` (ii) `90^(@)` (iii) `180^(@)`. ?

Two nicols are so oriented that the maximum amount of light is transmitted. To what fraction of its maximum value is the intensity of transmitted light reduced when the analyser is rotated through (i) 30^(@) (ii) 60^(@) ?

Two nicols prisms are so orientated that the maximum amount of light is transmitted. Two what fraction of itsmaximum value is the intensity of transmitted light reduced when the analyser is rotated through 30^(@) ?

A polariser and an analyser are oriented so that the maximum amount of lights is transmmitted. Fraction of its maximum value is the intensity of the transmitted through reduced when the analyzer is rotated through (intensity of incident light = I_(o) ) , a) 30^(@) , b) 45^(@) , c) 60^(@)

A polariser and analyser are so oriented that intensity of light transmitted is maximum. What fraction of maximum light is transmitted when analyser is rotated through an angle of 60^@ ?
