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^(@))

A polarizer-analyser set is adjusted such that the intensity of light coming out of the analyser is just 12.5 % of the original intensity of light incident on the polarizer. Assuming that the polarizer-analyser set does not absorb any light, the angle by which the analyser need to be rotated in any sense to increase the output intensity to double of the previous intensity, is :

An analyser is inclined to a polariser at an angle of 30^(0) . The intensity of light emerging from the analyser is (1)/(n) th of that is incident on the polariser. Then n is equal to

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

When the polariser and analyser are in the crossed position the intensity of the out coming light is

A polariser and an analyser are oriented so that maximum light is transmitted what will be the intensity of outcoming light when analyer is rotated through 60^(@) .

When a plane polarised light is passed through an analyser and analyser is rotated through 90^(@) , the intensity of the emerging light

The graph showing the dependence of intensity of transmitted light on the angle between polariser and analyser is

An analyser is inclined to a polariser at an angle of 30^(@) . The intensity of light emerging on the polariser. Then n is equal to

If 10% of intensity is passed from analyser, then, the angle by which analyser should be rotated such that transmitted intensity becomes zero. (Assume no absorption by analyser and polarizer).
