Radio signals are broadcast by what waves?
Radio waves are electromagnetic waves. Electromagnetic waves include waves such as X rays, ultraviolet light, visible light, infrared rays and so on, but you probably imagine radio waves to be quite different from these waves. Of the various kinds of electromagnetic waves, radio waves have a longer wave length than infrared rays, and are defined by the Radio Law as 'electromagnetic waves with a frequency of less than 3,000 GHz (3 THz)'Ultralow frequency radio wavesbelow 3kHzradio waves3kHz~3THz infrared rays3THz~380THz visible light380THz~790THz ultraviolet light790THz~105THz X rays105THz~107THz γ raysabove 107THzNames of radio waves Frequency Wave length Principal applications VLF(Very Low Frequency) 3kHz ~ 30kHz 100km ~ 10km LF(Low Frequency) 30kHz ~ 300kHz 10km ~ 1km Vessel / Airplane beacon MF(Medium Frequency) 300kHz ~ 3MHz 1km ~ 100m AM radio, Marine radio, Amateur radio HF(High Frequency) 3MHz ~ 30MHz 100m ~ 10m Shortwave broadcasting, Marine / Air radio, Amateur radio VHF(Very High Frequency) 30MHz ~ 300MHz 10m ~ 1m TV, FM, Fire radio, Police radio, Disaster PA radio network UHF(Ultra High Frequency) 300MHz ~ 3GHz 1m ~ 10cm Low power radio, Mobile-phone, Taxi radio, Amateur radio, TV, Wireless LAN SHF(Super High Frequency) 3GHz ~ 30GHz 10cm ~ 1cm Satellite broadcasting, Radar EHF(Extremely High Frequency) 30GHz ~ 300GHz 1cm ~ 1mm Satellite broadcasting, Radio astronomy, Radar submillimeter waves 300GHz ~ 3THz 1mm ~ 0.1mm
