State polarizer and analyser.

(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^(@) ?

If theta is the angle between the transmission axes of the polarizer and the analyser and l_0 be the intensity of the polarized light incident on the analyser, then Intensity of transmitted light through analyser would be

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

The axes of the polariser and analyser are inclined to each other at 45^(@) . If the amplitude of the unpolarised light incident on the polariser is A , the amplitude of the light transmited through the analyser is

The axes of the polariser and analyser are inclined to each other at 60^(@) . If the amplitude of the polarised light emergent through analyser is A. The amplitude of unpolarised light incident on polariser is

The angle between pass axis of polarizer and analyser is 45^(@) . The percentage of polarized light passing through analyser is

A polarizer-analyser set is a adjusted such that the intensity of light coming out of the analyser is just 12.5 % of the original intersity. Assuming that the polarizer – analyser set does not absorb any light the angle by which the analyser need to be rotated further to reduce the output intensity to be zero, is :

A polarizer-analyser set is a adjusted such that the intensity of light coming out of the analyser is just 12.5 % of the original intersity. Assuming that the polarizer – analyser set does not absorb any light the angle by which the analyser need to be rotated further to reduce the output intensity to be zero, is :

A polarizer - analyser set is adjusted such that the intensity of llight coming out of the analyser is just 36% of the original intensity. Assuming that the polarizer - analyser set does not absorb any light, the angle by which the analyser needs to be rotated further, to reduce the output intensity to zero, is (sin^(-1)((3)/(5))=37^(@))

If the angle between the pass axis of polariser and analyser is 45^(@) , write the ratio of intensities of original light and the transmitted light after passing through analyser.
