Suppose light comes onto a vertical polarizer perpendicular to the front surface. It passes through the first (vertical) polarizer and meets a second polarizer at an angle of 45°. After the second polarizer, the light continues onward to a 3rd polarizer that is positioned horizontally (or 90° from the vertical). If the intensity of the light coming into the first polarizer is 35 W/m^2, what would the intensity be after the 3rd polarizer?
