The applet simulates a string which can be 'plucked' or shaped with the mouse, have a driving force applied, be 'touched' to quiet a mode, or selected to vibrate at its fundamental frequency. Options include displaying phases, phasors, modes or phase cosines and adjusting the damping, force frequency (which can be set to resonance frequency), number of loads, simulation speed and tension. A sound option is also included, but only works in Windows. The sound applet only works in Microsoft Java, but a second applet is included with no sound for Netscape/Sun Java.
Please note that this resource requires Java.
This resource is part of 2 Physics Front Topical Units.
Topic: Periodic and Simple Harmonic Motion
Unit Title: Special Topics: The Physics of Music Pluck the virtual string on this simulation, watch, and listen. You can adjust the damping, tension on the string, and speed of the simulation. Set your own force frequency or click to see the resonant frequency. Click on "Shape String" to create your own harmonic. Editor's Note: This resource was designed to help students visualize the different modes of oscillation that happen when a string is plucked. The frequency of the harmonics is a multiple of the fundamental frequency. Teachers: see Reference Materials below for a free textbook written to introduce high school students to the physics of music. Link to Unit:
Topic: Wave Energy
Unit Title: The Physics of Sound This Java applet demonstrates waves on a vibrating string which is 'plucked' with the mouse. Options include adjusting the damping, force frequency (which can be set to resonance frequency), number of loads, simulation speed and tension. It is appropriate for use in AP physics or with students in a Part "B" high school course. Link to Unit:
