FIGURE 25-3 
-Figure 25-3 shows three polarizing disks having parallel planes with the direction of the transmission axis in each case. The disks are centered on a common axis. If a plane polarized beam of light is incident from left on the first disk with an intensity of 40 W/m2. What is the transmitted intensity coming out of the third disk, when θ1 = 10°, θ2 = 40°, θ3 = 70°?
A) 40 W/m2
B) 18 W/m2
C) 1.5 W/m2
D) 0 W/m2
E) 22 W/m2
