Wavelength is a property of an oscillation, vibration, or other regularly-repeating phenomenon. The wavelength of such a phenomenon is the reciprocal of an individual repetition of the repeating event. In the SI system of units, frequency is measured in Hertz (Hz), the number of repetitions in one second.

Frequency is inversely proportional to wavelength, which is a length measurement.

:

where c = 299,792,458 m/s (the speed of light) Rounding to convenient values for radio waves, frequency in megahertz (Mhz) divided by 300 gives the wavelength in meters:

:

Three systems of designating ranges of frequencies and wavelengths are in common use:
