Light polarisation

Polarising direction of a light wave

Natural light consists of electrical and magnetic waves. A light

wave "radiates" in one direction, known as the polarising

direction. The light wave is simultaneously overlaid by many

other light waves which all oscillate in the same axis. The

alignment is such that the other light waves seem vertical to the

propagation direction when viewed in the wave axis.
