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).
