Polarization, for light, refers to the orientation of the electric field in the electromagnetic disturbance. The magnetic field is always perpendicular to the electric field. Figure 10.1b and 1O.lc show vertical and horizontal polarization, respectively. Figure 10.1d depicts random polarization, which occurs when the direction of polarization changes rapidly with time, as it does in the light from most incandescent
