Additional Problems An unpolarized beam of light is sent into a stack of four polarizing sheets, oriented so that the angle between the polarizing directions of adjacent sheets is $30^{\circ} .$ What fraction of the incident intensity is transmitted by the system?
In Fig. 33-70, unpolarized light is sent into the system of three polarizing sheets, where the polarizing directions of the first and third sheets are at angles $\theta_{1}=30^{\circ}$ (counterclockwise) and $\theta_{3}=30^{\circ}$ (clockwise). What fraction of the initial light intensity emerges from the system?
Polarization In Fig. 33-41, a beam of light, with intensity 43 $\mathrm{W} / \mathrm{m}^{2}$ and polarization parallel to a $y$ axis, is sent into a system of two polarizing sheets with polarizing directions at angles of $\theta_{1}=70^{\circ}$ and $\theta_{2}=90^{\circ}$ to the $y$ axis. What is the intensity of the light transmitted by the two-sheet system?
