Chapter 1, Problem 95CP

The light incident on polarizing sheet ${\text{P}}_1$is linearly polarized at an angle of 30.00 with respect to the transmission axis of ${\text{P}}_1$ Sheet ${\text{P}}_2$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 ${\text{P}}_1$ . (a) What fraction of the incident light passes through ${\text{P}}_1$ ? (b) What fraction of the incident light is passed by the combination? (c) By rotating ${\text{P}}_2$ , 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 ${\text{P}}_1$ ?
