Two polarizing sheets are placed together to form a combination with transmission axes of the polarizers oriented at an angle to each other. With the polarizers so aligned, the amount of light that passes through the sheets is of the maximum possible intensity of plane polarized light that the combination can transmit. What percentage of unpolarized light would be transmitted through the combination?
A student places sheets and so that their transmission axes are at and , respectively. These angles are relative to the axis of polarization of a beam of linearly polarized light. This rotates the beam’s polarization by .
What fraction of light passes through ?
What fraction of light passes through both sheets?
The transmission angle for is changed to relative to the beam’s polarization axis. After the angle change, what fraction of light passes through both sheets?
Three polarizing sheets are placed parallel to each other. The transmission axis of the second sheet is oriented at relative to the transmission axis of the first sheet, and the transmission axis of the third sheet is oriented at relative to the transmission axis of the first sheet. What fraction of the intensity of an unpolarized light beam incident on the first sheet is transmitted by the third sheet?
