radio frequency bandA specified range of frequencies of electromagnetic waves. Radio frequency bands are classified as follows. These bands, based on multiples of 3, are a consequence of the speed of light being very nearly equal to 3 x 108 m s−1. Thus, VHF corresponds to free-space wavelengths 1–10 m and so on. Compare radar frequency band.
