PURPOSE: To show the relationship between the frequency and the wavelength in a rope stretched with fixed tension.

DESCRIPTION: Keeping the tension in the rope fixed (same weight on hook) and raising the frequency creates standing waves with shorter wavelength (more loops).

SUGGESTIONS: Using a 100-gram weight, harmonics 1, 2, 3, and 4 can be produced.See Question of the Week #264 and #265 for information on using this demonstration to enhance class involvement.

EQUIPMENT: Mounted rope wave generator with weights.

SETUP TIME: None.
