Polarizing windows, filters, etc. are often used to reduce the amount of light that enters the lens of a camera or into a room or a car. A library atrium has an overhead skylight that lets in too much light during the day which heats up the interior of the library far too much. The building engineer installs new double paned polarizing sky lights to reduce the intensity. If sunlight, which is unpolarized, has an average intensity of 1250 W/m2 what angle should the polarizing axis of the second pane of the window make with the polarizing axis of the first pane of the window in order to reduce the intensity of the sunlight to 33% of the original value
Required:
Assume that the first polarized window pane absorbs half of the intensity of the unpolarized light. The light between the first and second pane is polarized; what is the direction of its polarization? How does the intensity after the second polarizing filter relate to the angle of the filter and the intensity of light after the first polarizing filter?
