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.
There is also a free version available. The full version is optimized for iPad, and also allows you to create and delete objects, save your work, and change color schemes.
