Wave Speed Calculator

Physics guide

How to use the Wave Speed Calculator

Calculate wave speed and period from frequency and wavelength. The page also explains the wave speed and shows a practical example: 440 Hz and 0.78 m gives about 343 m/s.

  1. 1

    Enter your details

    Enter frequency and wavelength, then complete any other fields shown in the calculator.

  2. 2

    Check the calculation

    Review the result alongside the wave speed: Wave speed = frequency x wavelength.

  3. 3

    Compare scenarios

    Change one or more inputs to see how they affect the wave Speed Calculator result before you use the estimate.
