Quick answer
Wave speed = wavelength x frequency (v = lambda f).
v = lambda f
How to use the Wavelength Frequency Calculator
- 1Enter the wave's frequency in hertz.
- 2Enter the wave speed (343 m/s for sound in air, ~3e8 m/s for light in vacuum).
- 3Read the wavelength and period.

Frequently asked questions
What speed do I use for light?
Use 299792458 m/s for light in a vacuum, or divide by the refractive index for a medium.
How is period related to frequency?
Period is the inverse of frequency: T = 1/f.
