Wave Speed, Frequency & Wavelength

See a travelling wave pulse propagate along a 3D rope. Adjust frequency and wavelength to see how wave speed changes, with live frequency spectrum and the wave equation v = fλ.

Wave Speed

GCSE

The wave equation v = fλ relates wave speed, frequency, and wavelength. For any wave, increasing frequency decreases wavelength if speed is constant. Wave speed depends on the medium.

Frequency2.0Hz

Wavelength3.0m

📐 Formulas

v = f\lambdaWave speed = frequency × wavelength

T = \frac{1}{f}Time for one complete cycle
