Three polarizing filters are stacked, with the polarizing axis of the second and third filters at angles of 19.4 ∘ and 57.0 ∘, respectively, to that of the first. If unpolarized light is incident on the stack, the light has an intensity of 78.5 W/cm2 after it passes through the stack.

Part A

If the incident intensity is kept constant, what is the intensity of the light after it has passed through the stack if the second polarizer is removed?

Homework Answers

An unpolarized light bulb is dimmed by a stack of three polarizing filters. The middle filter is rotated 21.6 ∘ from the first filter, and the final filter is rotated 56.8 ∘ from the first filter. A light intensity of 71.5 W/cm2 exits from the stack of all three filters. The intensity can be increased and decreased by rotating the middle filter to other angles. What is maximum light intensity that can be obtained?
