Practice Problem on Polarizers

100o	170o	70o	140o

Polarized light at angle 100 degrees of intensity I₀ is incident from the left and passes sequentially through polarizers at angles 170, 70, and 140 degrees an indicated above. What is the intensity and polarization of the light exiting on the right? Give your answer in terms of I₀ to three decimal places. (Angles are measured from the vertical going counterclockwise.)

ANSWER = 0.000 I₀ at 140 degrees
