In the International System of Units, the derived unit of frequency; one (period or cycle of any periodic event) per second. Symbol: Hz
{i} family name; Heinrich Rudolph Hertz (1857-1894), German physicist, first person who produced electromagnetic waves in an artificial manner
German physicist who was the first to produce radio waves artificially. A unit of frequency equal to one cycle per second. See table at measurement. hertz Hz a unit for measuring the frequency of sound waves
A unit of frequency equal to one complete cycle each second, named after the physicist Heinrich Hertz
German physicist who with James Franck proved the existence of the stationary energy states postulated by Bohr (1887-1975) German physicist who was the first to produce electromagnetic waves artificially (1857-1894) the unit of frequency; one Hertz has a periodic interval of one second
born Feb. 22, 1857, Hamburg, Ger. died Jan. 1, 1894, Bonn German physicist. While a professor at Karlsruhe Polytechnic (1885-89), he produced electromagnetic waves in the laboratory and measured their length and velocity. He showed that the nature of their vibration and their susceptibility to reflection and refraction were the same as those of light waves, and he proved that light and heat are electromagnetic radiations. He was the first to broadcast and receive radio waves. In 1889 he was appointed professor at the University of Bonn, where he continued his research on the discharge of electricity in rarefied gases. The hertz (Hz), a unit of frequency in cycles per second, is named for him
