For an atom, the displacement of the center of the negatively charged electron cloud relative to the positive nucleus, which is induced by an electric field.
Polarization as a result of the displacement of anions and cations in opposite directions.
Polarization resulting from the alignment (by rotation) of permanent electric dipole moments with an applied electric field.
Right-Handed Polarized Wave
Defined as one receding from the observer and radiated by an electric vector rotating clockwise in a fixed plane that is in front of the observer and at right angles to the direction of propagation of the wave in question.
