Описание: Three polarizing filters are stacked, with the polarizing axis of the second and third filters at and , respectively, to that of the first. If unpolarized light is incident on the stack, the light has intensity 75.0 after it passes through the stack. 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?
