This website contains a Flash applet which simulates the motion of a vibrating string as well as ideas for activities involving this simulation. The end of the string can be moved using the mouse or driven by an oscillator to set up traveling or standing waves. The string is modeled as a series of interacting masses. The tension of the string, damping, and frequency and amplitude of the oscillator can be adjusted. Measurements can be made with rulers and a stop watch.
This item is part of a larger collection of simulations developed by the Physics Education Technology project (PhET). The simulations are animated, interactive, and game-like environments in which students learn through exploration.
Please note that this resource requires at least version 8 of Flash.
