Frequency & Wavelength Calculator
Move between frequency, wavelength and period using the wave speed you choose. The default speed is light in vacuum; change it for sound or another propagation medium.
Solved values
100,000,000 Hz
100 MHz
2.99792458 m wavelength
299.792458 cm · 2,997.92458 mm
10 ns period
Formula
f = v / λ · λ = v / f · T = 1 / f
Example: 100 MHz at 299,792,458 m/s gives a wavelength of about 2.998 m and a period of 10 ns.
Use cases
Useful for radio, electronics, optics, acoustics and classroom wave calculations. For a material medium, enter its applicable wave speed rather than assuming vacuum propagation.
Frequently asked questions
How do I convert frequency to wavelength?
Divide wave speed by frequency.
Can I calculate sound wavelength?
Yes. Replace the default wave speed with the sound speed appropriate to the medium and conditions.
