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.

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

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

Assertion : If theta is the angle between the planes of transmission of two analysers then the intensity of emergent light is proportional to cos^@ theta . Reason : In the propagation of electromagnetic waves, the angle between the direction of propogation and plane of polarisation is pi/2 .

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