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) ...

6. 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.

11. 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...
