In the figure, initiallyunpolarized light is sent through three polarizing sheets whosepolarizing directions make angles of θ1 = 40.0°, θ2 = 20.0°, and θ3= 32.0° with the direction of the y axis. Notice in the figure thatthe middle sheet is rotated in the opposite direction as the othertwo sheets. What percentage of the light's initial intensity istransmitted by the system? (no unit)
