Stationary Waves.

This program helps to clarify the mystery that if you add two travelling waves together you can get a stationary wave. It also shows clearly what a stationary wave is by slow motion animation.   Ideas included are: ...nodes and antinodes ...phase shift on reflection....the phase and amplitude of particles of the medium...how the amplitudes of the constituent waves are always equal and opposite at nodes.
