Wavelength Calculator – λ = v/f
Calculate wavelength from wave speed and frequency using λ = v/f.
How It Works
Enter wave speed in m/s and frequency in Hz. The calculator returns wavelength in meters. Results below 1 m are also displayed in cm and mm.
Formula
λ = v ÷ f
Frequently Asked Questions
What is wavelength?
Wavelength is the distance between successive crests (or troughs) of a wave. Visible light has wavelengths of roughly 380–700 nm.
What is the wavelength of FM radio waves?
FM radio waves (88–108 MHz) have wavelengths of about 2.8–3.4 m at the speed of light.
