1.7 Exercise 43

The light incident on polarizing sheet $\text{P}_{1}$ is linearly polarized at an angle of $30.0 °$ 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 $\text{P}_{2}$ is at $30.0 °$ with respect to $\text{P}_{1}$?
