Unpolarized Light of Intensity I₀ Passes Through Four Ideal Polarizing

question 13

Short Answer

Unpolarized light of intensity I₀ passes through four ideal polarizing sheets. The polarizing angle of each sheet is rotated 30° from the one before it, so that the last sheet is aligned at 90° to the first sheet. What is the intensity of the light emerging from the fourth sheet in terms of I₀?
