Please answer quickly Initially, unpolarized light with an intensity of 42.0 W/m2 is normally incident on three polarizers consecutively. Polarizer A is rotated - 20' with respect to vertical, Polarizer B is rotated +10° with respect to horizontal and polarizer C is rotated +35" with respect to vertical. What is the intensity of the light after passing through all three polarizers? A 11.4 W/m2 B 12.1 W/m2 C 24.1 W/m2 D 12.9 W/m2 E 106 W/m2
