Hypernyms ("radio emission" is a kind of...):

electromagnetic radiation; electromagnetic wave; nonparticulate radiation (radiation consisting of waves of energy associated with electric and magnetic fields resulting from the acceleration of an electric charge)

Hyponyms (each of the following is a kind of "radio emission"):

Hertzian wave (a former name for a radio wave; an electromagnetic wave of radio frequency generated by oscillations in an electric circuit)

sky wave (a radio wave that is reflected back to earth by the ionosphere or a communications satellite; permits transmission around the curve of the earth's surface)

ground wave (a radio wave propagated on or near the earth's surface)

radio signal (a radio wave used to transmit and receive messages)

carrier; carrier wave (a radio wave that can be modulated in order to transmit a signal)

short wave (a radio wave with a wavelength less than 100 meters (a frequency greater than 3 megahertz))

medium wave (a radio wave with a wavelength between 100 and 1000 meters (a frequency between 300 kilohertz and 3000 kilohertz))

long wave (a radio wave with a wavelength longer than a kilometer (a frequency below 300 kilohertz))

Holonyms ("radio emission" is a part of...):

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

 Context examples 

Because their rapid pulse of radio emission is so predictable, a large array of well-understood pulsars can be used to measure extremely subtle abnormalities, such as gravitational waves.
