The drawing shows two sheets of polarizing material. Polarizer 1 has its transmission axis aligned vertically, and polarizer 2 has its transmission axis aligned at an angle of 45° with respect to the vertical. Light that is completely polarized along the vertical direction is incident either from the far left or from the far right. In either case, the average intensity of the incident light is the same. Which one of the following statements is true concerning the average intensity of the light that is transmitted by the pair of sheets? (a) When the light is incident from either the left or the right, the transmitted intensity is one-half the incident intensity. (b) When the light is incident from either the left or the right, the transmitted intensity is one-fourth the incident intensity. (c) When the light is incident from the left, the transmitted intensity is one-half the incident intensity; when the light is incident from the right, the transmitted intensity is zero. (d) When the light is incident from the left, the transmitted intensity is one-fourth the incident intensity; when the light is incident from the right, the transmitted intensity is one-half the incident intensity. (e) When the light is incident from the left, the transmitted intensity is one-half the incident intensity; when the light is incident from the right, the transmitted intensity is one-fourth the incident intensity.
