, 1857–94, German physicist. He confirmed J. C. Maxwell's electromagnetic theory and in the course of experiments (1886–89) produced and studied electromagnetic waves (known also as hertzian waves, or radio waves).

hertz(herts) Symbol: Hz. The SI unit of frequency, defined as the frequency of a periodic phenomenon that has a period of one second. The frequency range of electromagnetic radiation is about 3000 Hz (very low frequency radio waves) to about 1022 Hz (high-frequency gamma rays).
Unit of frequency; a periodic oscillation has a frequency of n hertz if in 1 second it goes through n cycles. Also known as cycle per second (cps). Symbolized Hz.
A unit of frequency, abbr. Hz; one cycle per second.
The frequency of any cyclic repetition. One hertz (Hz) is one cycle per second. The number of cycles per second is expressed in hertz. Kilohertz (kHz) is a frequency of one thousand cycles per second. Megahertz (MHz) is a frequency of one million cycles per second. The term is named after Heinrich Hertz, a German physicist (1857–1894). Also called a cycle.
the derived SI unit of frequency; the frequency of a periodic phenomenon that has a periodic time of 1 second; 1 cycle per second.
