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.

There is also a full version of this app, called "Ripple Tank", which allows you to create your own experiments, save and load, and change colors. It is also optimized for iPad.

I was forced to

Imagine being forced to download an app because the teacher made you... I won’t dislike the app.

I found the “acoustic reflection” option useful for demonstrating seismic wave propagation to students. It is possible to simulate various imaging scenarios by moving the source around, and also by changing the location of the reflective interface. Fault diffractions can be simulated by changing the configuration of the reflector.

A fun way to learn about wave behavior

Made complex wave phenomena more intuitive. Great app, thanks!
