At the Brewster angle the reflected wave is

  • A.circularly polarised whatever the incident polarisation
  • B.reversed in phase for both polarisations
  • C.completely polarised in one direction
  • D.of zero amplitude for both polarisations

Answer: C

One of the two polarisations suffers no reflection at that angle, so the reflected wave contains only the other. Polarising sunglasses exploit the fact that light reflected from a horizontal surface is largely horizontally polarised.
