The time average of S over one or more cycles is called the wave intensity, I, which gives the very important result that the intensity of a light wave is proportional to the square of the amplitude of the electric or magnetic fields: 22 max max ...

www.yorku.caLight is a transverse electromagnetic wave. Its prop-agation can therefore be explained by recalling the properties of transverse waves. Picture a transverse wave as traced by a point that oscillates sinusoidally in a plane, such that the direction of oscillation is perpendicular to the direction of propagation of the wave.

Uniform Plane Waves - Rutgers University
www.ece.rutgers.eduUniform Plane Waves 2.1 Uniform Plane Waves in Lossless Media The simplest electromagnetic waves are uniform plane waves propagating along some fixed direction, say the z-direction, in a lossless medium {,μ}. The assumption of uniformity means that the fields have no dependence on the transverse coordinates x,yand are functions only of z,t.
