Wavelength Calculator
Calculate wavelength, frequency, or wave speed from the wave equation.. Kostenlos, ohne Anmeldung, funktioniert im Browser.
Über Wavelength Calculator
This free wavelength calculator uses the wave equation (λ = v / f) to find wavelength, frequency, or wave speed. Enter any two values to calculate the third. Supports electromagnetic waves (light, radio), sound waves, and custom wave speeds. Includes preset speeds for light in vacuum and sound in air.
Häufig gestellte Fragen
What is the wavelength formula?
Wavelength (λ) = Wave Speed (v) ÷ Frequency (f). For electromagnetic waves in vacuum, v = 299,792,458 m/s (speed of light).
What units are supported?
Wavelength: meters, centimeters, millimeters, micrometers, nanometers, angstroms. Frequency: Hz, kHz, MHz, GHz, THz. Speed: m/s, km/s, km/h.
Can I calculate sound wavelengths?
Yes. Select 'Sound in Air' preset (343 m/s at 20°C) or enter a custom speed. Useful for acoustics, speaker design, and room treatment calculations.
