Answer to Question #41320 in Optics for qwerty

Question #41320
On a polarizing sheet a mixture of plane polarised and unpolarised light falls normally. On rotating the polarising sheet about the direction of the incident beam, the transmitted maximum and minimum intensities vary by a factor 4. The ratio of the intensities of polarised and unpolarised light is ?

Intensity of unpolarized light always halved and it does not depend on the polarizer orientation. Thus we write I_u/2. Linearly polarized light passes through polarizer without change when direction of polarizer's axis and polarization of light coincide, thus we add I_p to I_u/2 to obtain I_max. And when polarizer's axis and polarization of light are orthogonal, polarized light does not pass through polarizer. So we write I_min = 0 + I_u/2 = I_u/2.
