A light has amplitude A and angle between analyser and polariser is `60^(@)`. Light is reflected by analyser has amplitude

(a) State law of Malus. (b) Draw a graph showing the variation of intensity (I) of polarised light transmitted by an analyser with angle (theta) between polariser and analyser. (c ) What is the value of refractive index of a medium of polarising angle 60^(@) ?

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

What is the angle between the plane of polariser and that of analyser to reduce the transmitted light intensity to half ?
