The vibration of a guitar string provides a good example of standing waves. Holding down the string at a fret forces a node in the vibrating string and produces a standing wave with the appropriate wavelength.


This Demonstration lets you explore and visualize the different harmonics that can be produced on a guitar by forcing a node at various fret positions.




Snapshot 1: 3rd harmonic

Snapshot 2: 4th harmonic

Snapshot 3: 5th harmonic

Variables: : amplitude, : wavelength, : angular frequency, : string length, : harmonic number, : string tension, : string density
