In the Figure, the Orientation of the Transmission Axis for Each

Multiple Choice

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
