Scattered light in the atmosphere is often partially polarized. The best way to determine whether or not light from a particular direction in the sky shows polarization is to
 a. diffract the light through a single slit.
  b. squint while looking in that direction.
  c. rotate a piece of polaroid film about an axis parallel to the ray while looking through it in that sky direction.
  d. rotate a piece of polaroid film about an axis perpendicular to the ray while looking through it in that sky direction.
  e. reflect the rays from that direction on a shiny metal surface.

Question 2

Polarized light is to have its polarization plane rotated by 90. In which of the following cases does the final beam have the greatest intensity?
 a. 3 polarizing filters, each rotate beam by 30.
  b. 2 polarizing filters, both rotate beam by 45.
  c. 1 polarizing filter, rotating beam by 90.
  d. None of the above, polarized light can't be rotated.
