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
