Question

If the angle between the planes of the polarizer and analyser is 60
degree, by what factor does the intensity of the transmitted light
change when passing through the analyser

Apurba Paul · Accepted Answer

Intensity transmitted after analyzer is
I=I0 cos2θ=I0 cos260°=I02, so the intensity will
be half while passing through the analyzer
