In the figure, the orientation of the transmission axis for each of three polarizing sheets is labeled relative to the vertical direction. A beam of light, polarized in the vertical direction, is incident on the first polarized with an intensity of 1000 W/m2. What is the intensity of the beam after it has passed through the three polarizing sheets when θ1 = 30°, θ2 = 30° and θ3 =60°?
A) 141 W/m2
B) 316 W/m2
C) 433 W/m2
D) 563 W/m2
E) 188 W/m2
