Item Picture
published by the PhET
You can visualize sound with this PhET simulation from the University of Colorado. You can vary the frequency and wavelength to see how the sound wave changes and how it propagates. Also, you can hear the sound that would be produced.

This simulation is part of a large and growing collection developed by the Physics Educational Technology Project using research-based principles.

Please note that this resource requires Java.
