The light incident on polarizing sheet P1 is linearly polarized at an angle of 30.0∘ with respect to the transmission axis of P1. Sheet P2 is placed so that its axis is parallel to the polarization axis of the incident light, that is, also at 30.0∘ with respect to P1.
(a) What fraction of the incident light passes through P1 ?
(b) What fraction of the incident light is passed by the combination?
(c) By rotating P2, a maximum in transmitted intensity is obtained. What is the ratio of this maximum intensity to the intensity of transmitted light when P2 is at 30.0∘ with respect to P1 ?
