The hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose expression in terms of SI base units is s , meaning that one hertz is the reciprocal of one second. It is named after Heinrich Rudolf Hertz … See more The hertz is equivalent to one cycle per second. The International Committee for Weights and Measures defined the second as "the duration of 9192631770 periods of the radiation corresponding to the transition between … See more The hertz is named after the German physicist Heinrich Hertz (1857–1894), who made important scientific contributions to the study of See more Higher frequencies than the International System of Units provides prefixes for are believed to occur naturally in the frequencies of the quantum-mechanical vibrations of massive particles, although these are not directly observable and must be inferred through … See more • Alternating current • Bandwidth (signal processing) • Electronic tuner • FLOPS See more Sound and vibration Sound is a traveling longitudinal wave, which is an oscillation of pressure.
