Four linear polarizers are stacked so that each is at a 30 degree angle to the one before it, so that the final output polarization is 90 degrees to the first one. If unpolarized light of intensity I(o) is incident on theh stack, what is the intensity of the transmited light? How would this change if the incident light is right circualrly polarized instead of unpolarized?
