pitch, inmusic, position of a singlesoundin the complete range of sound. Sounds are higher or lower in pitch according to thefrequencyofvibrationof the sound waves producing them. A high frequency (e.g., 880hertz[Hz; cycles per second]) is perceived as a high pitch and a low frequency...

Radio frequency is measured in units calledhertz(Hz), which represent the number of cycles per second when a radio wave is transmitted. One hertz equals one cycle per second; radio waves range from thousands (kilohertz) to millions (megahertz) to billions (gigahertz) of cycles per second. In...
Frequency is measured in units of Hertz (Hz), or cycles per second: 1 megahertz (MHz) = 106 Hz, and 1 gigahertz (GHz) = 109 Hz. In the three decades from when one of the authors' families bought an Apple II+ computer to the present time of writing, microprocessor clock frequencies ...
The meaning of TURNOVER FREQUENCY is the frequency (as 500 cycles per second) at which the transition is made from constant velocity recording to constant amplitude recording in making phonograph records.
The meaning of ANGULAR FREQUENCY is frequency of a periodic process (as electric oscillation or sound vibration) expressed in radians per second, equivalent to frequency in cycles multiplied by 2π.
