  Hertz - Wikipedia, the free encyclopedia
The hertz (symbol: Hz) is the SI unit of frequency.
One hertz is defined as the reciprocal second.
The lower the hertz, the deeper the level of noise, the higher the hertz, the louder (high-pitched) level of noise.

 Heinrich Rudolf Hertz - Wikipedia, the free encyclopedia
Hertz was born in Hamburg, Germany, to Gustav Ferdinand Hertz, whose father converted from Judaism to Lutheranism and married into a Lutheran family, and Anna Elisabeth Pfefferkorn, herself a Lutheran.
Hertz had always had a deep interest in meteorology probably derived from his contacts with Willhelm von Bezold (he was Hertz's professor in a laboratory course at the Munich Polytechnic in the summer of 1878).
Hertz, however, did not contribute much to the field himself except for some early articles as an assistant to Helmholtz in Berlin, including research on the evaporation of liquids, a new kind of hygrometer, and a graphical means of determining the properties of moist air when subjected to adiabatic changes.

 Reflections on Hertz and the Hertzian Dipole
Hertz himself pointed out only that his assumed solution "corresponds" (in the region that was later termed the near field) to an oscillating electrostatic dipole, and to an oscillating current as well.
Hertz absorbed from his mentor the notion that proper and effective physical theories are built on the basis of potential functions that represent the interaction at a given moment in time between two physical objects.
Hertz was quite familiar with this possibility from Helmholtz’s work, and he clearly did not like it, since in 1884 he had produced his version of Maxwell’s equations without using the ether at all.

 Adventures in CyberSound: Hertz, Heinrich Rudolph
Hertz's condenser was a pair of metal rods, placed end to end with a small gap for a spark between them.
With this oscillator, Hertz solved two problems: (1) Timing Maxwell's waves (he had conclusively demonstrated, what Maxwell had only theorized: that the velocity of radio waves was equal to the velocity of light), and (2) How to make the electric and magnetic fields detach themselves from wires and go free as "Maxwell's waves".
In 1889 Hertz was appointed professor of physics at the University of Bonn, where he continued his research on the discharge of electricity in rarefied gases.

Hertz, Heinrich Rudolf (1857-1894), German physicist, born in Hamburg, and educated at the University of Berlin.
Hertz proved that electricity can be transmitted in electromagnetic waves, which travel at the speed of light and which possess many other properties of light.
Before Hertz gained professorships in Karlsruhe and Bonn, he had studied under the famous scientist Hermann von Helmholtz in Bonn, and it was Helmholtz who encouraged Hertz to attempt to win the science prize that led to some of Hertz's most important discoveries.
