Unpolarized light of intensity 32 Wm^(-3) passes through three polarizers such that the transmission axis of the last polarizer is crossed with the first. If the intensity of the emerging light is 3 Wm^(-2) , what is the angle between the transmission axes of the first two polarizers ? At what angle will the transmitted intensity be maximum ?
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 .
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 orientation between a polariser and an analyser is such that the intensity of transmitted light is maximum. On rotating the analyser through 60^@ , what fraction of maximum light will be transmitted?
When the polariser and analyser are in the crossed position the intensity of the out coming light is
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).
