A simulation of a ripple tank, or wave tank. Make waves with your finger, or view examples including such wave phenomena as interference, diffraction (single slit, double slit, etc.), refraction, resonance, and the Doppler effect.

Create your own experiment and save it for future reference. Create objects (boxes, ellipses, walls, media) and move them around. You can also record videos.

Good teaching tool

It’s a good simulator to study wave interference without an actual ripple tank. My suggestions to improve it further would be to 1) allow the user to move and nudge the point sources with the keyboard arrows and perhaps provide the option to snap them to a hidden grid for precise positioning of the sources, 2) provide explanations and notes or links to online sources about the different setups for study, such as what is a phased array or a coupled cavity, 3) allow the user to export a recording as a Quicktime movie besides the current default avi file, and 4) give the user the option to change the dimensions of the tank besides the current, fixed 600 x 600 pixel square.
