The electromagnetic spectrum is a range of frequencies, wavelengths and photon energies covering frequencies from below 1 hertz to above 1025Hz corresponding to wavelengths which are a few kilometres to a fraction of the size of an atomic nucleus in the spectrum of electromagnetic waves. 0000003812 00000 n 0000077339 00000 n The radio spectrum is the radio frequency (RF) portion of the electromagnetic spectrum. This chart is not the ‘mixing law.’ Instead, it’s a good reference to get you started on thinking about where your performances sit in your mix—so use it accordingly.
