This applet simulates a propagating electromagnetic wave. The displays show a three-dimensional projection of the wave (with control over viewing angle) and the x and y components of the incoming (blue) and outgoing (magenta) waves. The incoming wave is chosen by specifying the amplitudes in the x and y components, and the phase difference between the x and y components. A polariser or a wave plate can be placed in the beam.
