3. 
   radio frequency or radiofrequency
   <physics> Term used to describe electromagnetic radiation with frequencies less than infrared, but greater than audio frequencies, i.e., greater than about 15,000 Hz. Wavelengths are therefore less than about 20,000 km and greater than about 0.01 mm. (These numbers are not precise.) ... (09 Oct 1997) ...

   Radio frequency
   `Radio frequency` (`RF`) is a frequency or rate of oscillation within the range of about 3 Hz to 300 GHz. This range corresponds to frequency of alternating current electrical signals used to produce and detect radio waves. Since most of this range is beyond the vibration rate that most mechanical systems can respond to, RF usually refers to oscillations in electrical circuits or electromagnetic radiation.

   Radio Frequency
   In comparison with other electromagnetic waves or oscillations, radiofrequencies are low frequencies (H103 - 1010). The frequency of the accelerating electric field falls in the range of radio frequencies and RF in an accelerator refers to this accelerating field.

    radio frequency
    radio frequency, range of electromagnetic waves with a frequency or wavelength suitable for utilization in radio communication. Some of these waves serve as carriers of the lower-frequency audio waves; others are modulated by video or digital information. Short waves have relatively high frequencies...
