    Light is polarized. The plane of polarization is specified with reference to the direction of propagation and the direction of the oscillating electric (E) or magnetic (H) field, which always oscillate perpendicularly to each other. In this view, the electric field is polarized vertically and the magnetic field horizontally, but they could be interchanged, or polarization could be in any oblique meridian.
