A derivation similar to the original derivation is given in Ref. 6. PMD 14 1/14/2009, 7:18 PM 15 What is Light? u P D (a) P Associated with a light wave are changing electric and magnetic fields; the changing magnetic field produces a timeand space-varying electric field; and the changing electric field produces a time- and space-varying magnetic field, and this results in the propagation of the electromagnetic wave even in free space.
10 THE POLARIZATION OF A PHOTON Let us consider the incidence of a plane electromagnetic wave on a polaroid whose pass axis is along the y direction (see Fig. 13); obviously, the electric vector of the transmitted wave would be along the y direction (see Chap. 22). Thus, if the electric vector associated with the incident wave oscillates along the x axis, the wave will be absorbed by the polaroid. On the other hand, if the electric vector oscillates along the y axis, it will just pass through the polaroid.
