Practice Problem on Polarizers
incoming at 20 deg. 90 deg. 120 deg. 130 deg.
20o 90o 120o 130o

Polarized light at angle 20 degrees of intensity I0 is incident from the left and passes sequentially through polarizers at angles 90, 120, and 130 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 = 0.085 I0 at 130 degrees
