How to use the Wave Speed Calculator

The Wave Speed Calculator works out your wave speed in an instant. Enter frequency and wavelength and the result updates as you type — it is free, needs no sign-up, and runs entirely in your browser so your figures stay private.

  1. Enter the frequency.
  2. Enter the wavelength.
  3. Read off your wave speed — the calculator updates automatically, with no button to press.

Formula

The Wave Speed Calculator uses the formula:

Wave speed = Frequency × Wavelength

Worked example

For example, with frequency of 50 Hz and wavelength of 6 m, the wave speed is 300.0000.

Inputs used
Frequency 50 Hz
Wavelength 6 m
Results
Wave speed 300.0000

Frequently asked questions

Multiply frequency by wavelength: v = f × λ. A 50 Hz wave of 6 m wavelength travels at 300 m/s.

It states that wave speed equals frequency times wavelength, linking how often and how far each cycle moves.

Yes. It applies to all waves, though light's speed is fixed and sets the relationship between its frequency and wavelength.

Metres per second when frequency is in hertz and wavelength in metres.
