Wave Relation Calculator

Convert between wave speed, frequency and wavelength.

About Wave Relation Calculator

Wave relations for Wave Relation link speed, frequency and wavelength so any two determine the third, and period is the reciprocal of frequency. The same wave relationship governs sound, light and water, so one formula serves all of them.

Formula

Wave Relation

Speed = frequency x wavelength; period = 1 / frequency

hertz: Cycles per second
wavelength: Distance between successive wave crests

Worked example

With the default values below, Wave Relation Calculator returns Wave Speed of 343.20. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 3 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or fees or charges into account.
Figures are rounded for display to 5 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

How is Wave Relation calculated?

Speed = frequency x wavelength; period = 1 / frequency Wave relations for Wave Relation link speed, frequency and wavelength so any two determine the third, and period is the reciprocal of frequency.

Why does Wave Relation matter?

The same wave relationship governs sound, light and water, so one formula serves all of them.

What values do I need to enter?

This calculator takes 3 inputs: Frequency, Wavelength, Wave speed. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
