Frequency Ranges

Frequency (in MHz) = 300 / Wavelength (in m)

and

Frequency (in GHz) = 30 / Wavelength (in cm)

(For greater accuracy use 299.79/Wavelength)

Electromagnetic waves with wavelengths under 1 mm are called light. See "Visible Spectrum"

The whole used Frequency spectrum reaches from 100 Kilohertz (kHz) to 12.5 Gigahertz

(GHz).
