Practice Problem on Polarizers
incoming unpolarized 120 deg. 130 deg. 50 deg.
unpolarized 120o 130o 50o

Unpolarized light of intensity I0 is incident from the left and passes sequentially through polarizers at angles 120, 130, and 50 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 = 0.015 I0 at 50 degrees
