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^(@))

A polarizer analyzer set is adjusted such that the intensity of ligth coming out of the analyzer is just 10% of the original intensity. Assuming that the polarizer analyzer set does not asorb any light, the angle by which the analyzer needs to be rotated further to reduce the output intensity to be zero is

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^(@) . The intensity of light emerging from the analyser is 1"/"n th of that is incident on the polariser. Then n is equal to
