Three polarizing filters are stacked, with the polarizing axis of the second and third filters at angles of 24.0° and 62.0°, respectively, to that of the first. If unpolarized light is incident on the stack, the light has an intensity of 69.5 W/cm² after it passes through the stack. Part A If the incident intensity is kept constant but the second polarizer is removed, what is the intensity of the light after it has passed through the stack?
