13 The average intensity of light emerging from a polarizing sheet is 0.787 W/m2, and the average intensity of the horizontally polarized light incident on the sheet is 0.922W/m2. Determine the angle that the transmission axis of the polarizing sheet makes with the horizontal.

Answer #1

The transmission factor is Iout/Iin = (cos(theta))^2
Thus theta = arccos(sqrt(0.787/0.922)) = 22.4979 deg.
