An unpolarized light beam with intensity I0 is first passed through an ideal polarizer. At this instant, the light is polarized. We then pass that light through 3 more identical polarizers having parallel axes of transmission to each other. If the transmission axis of the final polarizer makes an angle of 35 ∘∘ with the electric field direction of the polarized light, what is the intensity of the emerging light?

law: I = I0 cos²θ where I0 is the intensity of the polarized light beam just before entering the polarizer
law: I = I0 cos²θ where I0 is the intensity of the polarized light beam just before entering the polarizer, I is the intensity of the transmitted light beam immediately after passing through the polarizer, and is the angular difference between the polarization angle of the incident beam and the transmission axis of the polarizer. After passing through the polarizer, the transmitted light is polarized in the direction of the transmission axis of the polarizing filter. Part DOne way to produce a beam of polarized...
