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
