Three ideal polarizing filters are stacked, with the polarizingaxis of the second and third filters at 29.0and 58.0, respectively,to that of the first. If unpolarized light is incident on thestack, the light has intensity 110 after it passes through thestack.

If the incident intensity is kept constant, what is the intensityof the light after it has passed through the stack if the secondpolarizer is removed?

Please help!
