Polarization: The following items are positioned in sequence: A source of a beam of natural light of intensity I0, three ideal polarizers A, B, and C; and an observer. Polarizer axis angles are measured clockwise from the vertical, as viewed by the observer. The axis angle of polarizer A is set at 0° (vertical), and the axis angle of polarizer C is set at 50°. Polarizer B is set so that the beam intensity at the observer is a maximum. What is the axis angle settings of polarizer B?

A. 0°
B. 25°
C. 50°
D. 75°
E. 100°


Answer: B
