D)all of the above
E)none of the above

Question

Quizplus · Accepted Answer

When the axes of the two polaroids are perpendicular to each other, the second polaroid blocks all the light that has passed through the first polaroid, and hence no light passes through the pair of polaroids. When the axes are parallel, all the light passes through both the polaroids as the polaroids allow only the component of light vibrating in their plane of polarization. When the axes are at 45 degrees, some light passes through the polaroids, but the intensity of the transmitted light is reduced as the axis of the second polaroid is not completely perpendicular to the plane of polarization of the light that passed through the first polaroid.
