Polarization: A vertically polarized beam of light of intensity 100 W/m2 passes through two ideal polarizers. The transmission axis of the first polarizer makes an angle of 20.0° with the vertical, and the transmission axis of the second one makes an angle of 40.0° with the vertical. What is the intensity of the light after it has passes through both polarizers?
A. 22.2 W/m2
B. 44.4 W/m2
C. 66.6 W/m2
D. 78.0 W/m2
E. 11.7 W/m2
