Ripple Tank Lite - com.falstad.ripplefree - Android apps - apk download

Description

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.

But it was fun. Did you get a seizure yet? It’s hypnotizing

Wonderful free app that shows clearly how waves propagate from various sources— point source, two sources, dipole, etc — then how the waves reflect and interfere. Several options to customize. You can also “stick your finger in the water” and generate new waves that mix in with the provided waves. You can see things that would be a lot of trouble to set up in a lab. Too bad several snotty schoolchildren were assigned to download it and failed to appreciate what they could learn and experience — their reviews are worthless.

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

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

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.
