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^@`?

Draw a graph showing the variation of intensity of polarized light transmitted by an analyser.

Two polarised are placed at 90^@ to each other and the intensity of transmitted light is zero. What will be the intensity of transmitted light, when one or more polaroids is placed between these two bisecting the angle between them? Take intensity of unpolarised light as I_0 ?

If the angle between the pass axis of a polariser and the analyser is 45^@ ,write the ratio off the intensitties of original light and the transmitted ligth after pasing through the analyser.

Two polaroids are aligned,so that the intentsity of light emerging out of them is maximum.Through what angle one of them should be rotated ,so that the intensity of light emerging out of them is reduced to half.

What is the maximum frequency which can be transmitted by ground waves ?

An unpolarised beam of light of intensity I_0 is incident on a combination of two polaroids.Find the net intesity of light of intensity transmitted by the combinatin,when the pass axis of the two polaroids are inclined to each other at an angle of 60^@ .

If the angle between the planes of the polariser and analyser is 60^@ , by what factor does the intensity of the transmitted light change when passing through the analyser.

Two polaroids are set in corossed positions.A third polaroid is placed between the two making an angle theta with the pass axis of the first polaroid.Write the expession for the intensity of light trnasmitted from the second polaroid .In what orientations will the transmitted intenesity be minimum adn
