Question: A vertically polarized photon is incident on a pair of polarizers. The first one, P1, can be rotated to have its transmission axis oriented at any angle θ with the vertical. The second one, P2, has its transmission axis oriented horizontally.
a. How will the intensity of the beam of photons emerging from P2 vary as a function of θ as P1 is rotated?
b. At what angles of P1 will the transmission through P2 be a maximum?
c. How will your answers change if the incident beam of photons is unpolarized?
