Farily self evident. Longitudinal and transverve pulses and sine waves.
When there are two waves up top, the third wave is their sum. Wavelength and
phase of the second wave can be altered with the sliders, and the direction
of the second wave changed with the radio buttons (so standing waves can be
easily made in the sum).
There is also a scientific calculator one can access with the CALC button.
