The following are positioned in sequence: A source of a beam of natural light of intensity ; three ideal polarizers A, B, and C; and an observer. Polarizer axis angles are measured clockwise from the vertical, from the perspective of the observer. The axis angle of polarizer A is set at zero degrees (vertical), and the axis angle of polarizer C is set at 50 degrees. In the above situation, polarizer B is set so that the beam intensity is zero at the observer. The two possible axis angle settings of polarizer B are:
