radio frequency - an electromagnetic wave frequency between audio and infrared

extremely low frequency, ELF - below 3 kilohertz

very low frequency, VLF - 3 to 30 kilohertz

LF, low frequency - 30 to 300 kilohertz

medium frequency, MF - 300 to 3000 kilohertz

high frequency, HF - 3 to 30 megahertz

very high frequency, VHF - 30 to 300 megahertz

UHF, ultrahigh frequency - 300 to 3000 megahertz

SHF, superhigh frequency - 3 to 30 gigahertz

EHF, extremely high frequency - 30 to 300 gigahertz

spectrum - an ordered array of the components of an emission or wave

actinic radiation, actinic ray - electromagnetic radiation that can produce photochemical reactions

gamma radiation, gamma ray - electromagnetic radiation emitted during radioactive decay and having an extremely short wavelength

infrared spectrum - the spectrum of infrared radiation

light, visible light, visible radiation - (physics) electromagnetic radiation that can produce a visual sensation; "the light was filtered through a soft glass window"

line - a single frequency (or very narrow band) of radiation in a spectrum

microwave - a short electromagnetic wave (longer than infrared but shorter than radio waves); used for radar and microwave ovens and for transmitting telephone, facsimile, video and data

microwave spectrum - the part of the electromagnetic spectrum corresponding to microwaves

radio spectrum, radio-frequency spectrum - the entire spectrum of electromagnetic frequencies used for communications; includes frequencies used for radio and radar and television

ultraviolet spectrum - the spectrum of ultraviolet radiation

color spectrum, visible spectrum - the distribution of colors produced when light is dispersed by a prism
