Three polarizing filters are stacked, with the polarizing axis ofthe second and third filters at angles of 22.2^\circ and 68.0^\circ, respectively, to that of thefirst. if unpolarized light is incident on the stack, the light hasan intensity of 75.5 w/cm^2 after it passes through thestack.
a) if the incident intensity is kept constant, what is theintensity of the light after it has passed through the stack if thesecond polarizer is removed?
