The polarization behavior of light is best explained by considering light to be what?

The polarization behavior of light is best explained by considering light to be an electromagnetic wave. This perspective highlights that light consists of oscillating electric and magnetic fields that are oriented perpendicular to each other and to the direction of propagation. When light is polarized, the orientation of these electric field oscillations becomes restricted, resulting in specific polarization states such as linear, circular, or elliptical polarization.
