Polarization: As shown in the figure, the orientation of the transmission axis for each of three ideal polarizing sheets is labeled relative to the vertical direction. A beam of light, polarized in the vertical direction, is incident on the first polarizer with an intensity of 1.00 kW/m2. What is the intensity of the beam after it has passed through the three polarizing sheets when ?1 = 30°, ?2 = 30°, and ?3= 60°?
A. 141 W/m2
B. 316 W/m2
C. 433 W/m2
D. 563 W/m2
E. 188 W/m2
