Three ideal polarizing filters are stacked, with the polarizing
axis of the second and third filters at 29.0? and 55.0?,
respectively, to that of the first. If unpolarized light is
incident on the stack, the light has intensity 75.0W/cm2 after it
passes through the stack.
1. 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?
