Two polarizing films are crossed with their transmission axes making an angle of θ = 20° with each other. The vectors that represent the plane-polarized wave train passed by the second polarizing film are
A) 1 - 1'.
B) 2 - 2'.
C) 3 - 3'.
D) 4 - 4'.
E) None of these is correct because no light passes through the second disk.
