published by the PhET
This PhET simulation, from the University of Colorado, allows you to explore the properties of water, sound, and light waves. you can measure the wave speed with a stopwatch and ruler, and you can investigate interference and diffraction with movable detectors and customizable slit widths and spacings. You can even change the view to observe from above or from the side.
