Formula and methodology
Formula: Wavelength λ = wave speed v ÷ frequency f; period T = 1 ÷ f.
Wavelength depends on both frequency and propagation speed. The speed is an explicit field so the page works for vacuum, materials, sound, and other signals without assuming one environment.
This result follows the calculator's declared inputs, precision, validation boundaries, and model limits.
Input contract
- Frequency — cycles/time; minimum 1.0E-6; maximum 1000000000000000
- Wave speed — length/time; Enter the speed for the medium or signal; the default is the vacuum speed in m/s.; minimum 1.0E-6; maximum 1000000000000
Worked example
| Input | Value |
|---|---|
| Frequency | 100000000 |
| Wave speed | 299792458 |
Wavelength = 2.99792458 length units, period = 0.00000001 time units, and wavenumber = 0.3335640952 per length unit.
Assumptions and limits
- Frequency and wave speed use compatible time and length units.
- Frequency and wave speed are positive.
- The wave is modeled with λ = v/f and a stable supplied speed for the scenario.
- Dispersion, modulation, measurement error, and medium-specific behavior are not inferred.
