Unpolarized light with an intensity of 680 W / m2 is incident on a polarizer with an unknown axis. The light then passes through a second polarizer with has an axis which makes an angle of 79.5° with the vertical. After the light passes through the second polarizer, its intensity has dropped to 196 W / m2.

1) What is the angle between the axes of the polarizers in degrees?

2) What angle from the vertical is the first polarizer's axis? (Assume that it is closer to vertical than the 2nd polarizer - i.e., a smaller angle from the vertical than the 2nd polarizer.)

An unpolarized light beam of 800 W/m2 is incident on an ideal pair of crossed linear polarizers. Crossed polarizers indicate that the transmission axes of the polarizers are at 900 to one another. Now, a third polarizer is inserted between the other two with its transmission axis at 450 to that of each of the others. Determine the emerging intensity a) before and b) after the insertion of the third polarizer c) explain the results of parts a) and b).
