Question

Light is reflected off the rear windshield of a car. At what position of the polarizer is the transmitted intensity at a minimum, and why? (the following numbers in degrees)

***A B C are incorrect so I'm stuck between D and E***

A) 90 and 270 , because the polarizations of the plane waves are perpendicular to the axis of the Polaroid.
  
B) 0 and 180 , because light reflected from the windshield is parallel with the Polaroid axis.
  
C) 0 and 180 , because the polarization of the reflected light is crossed with the Polaroid axis.
  
D) At all positions, the intensity will be minimum because light transmits through two surfaces.
  
E) 90 and 270 , because the polarization of the reflected light is parallel with the axis of the Polaroid.

Explanation / Answer

90 and 270 , because the polarization of the reflected light is parallel with the axis of the Polaroid
