What this calculator does
Wave speed, frequency & wavelength works out relates the three properties of any wave. Enter your own figures above and the answer updates as you type: nothing is fixed in the code, so the result reflects exactly the numbers you supply.
The formula this calculator evaluates is printed under the tool and explained below, so you can check the working by hand or reuse it in a spreadsheet.
The formula
Formulav = f·λ; for light v = c = 299,792,458 m/s; period T = 1/f
The inputs explained
| Field | What to enter |
|---|---|
| Frequency (Hz) | A number, measured in Hz. Starts at 440. |
| Wave speed (m/s) | A number, measured in m/s. Starts at 343. |
Worked examples
Every figure in the tables below is produced by this page’s own calculator at build time, so the numbers and the tool always agree. Select any row to load that scenario.
How the answer changes with frequency
Every other input is held at the calculator’s starting values while frequency varies. Select any row to load that scenario into the calculator.
