Heinrich Rudolf Hertz (/ h ɜːr t s /; German: [ˈhaɪ̯nʁɪç ˈhɛɐ̯ts]; 22 February 1857 – 1 January 1894) was a German physicist who first conclusively proved the existence of the electromagnetic waves predicted by James Clerk Maxwell's equations of electromagnetism.The unit of frequency, cycle per second, was named the "Hertz" in his honor.
In November 1886 Heinrich Hertz became the first person to transmit and receive controlled radio waves. Considering how indispensable his wireless transmissions quickly became, it seems a little odd looking back that he had no practical purpose in mind for the radio or Hertzian waves he discovered.
The first spark gap oscillator built by German scientist Heinrich Hertz around 1886, the first radio transmitter, with which Hertz discovered radio waves. It consists of two 1 meter copper wires, supported on wax insulators, with a 7.5 mm spark gap between the inner ends, with 30 cm zinc balls on the outer ends.
German physicist Heinrich Hertz discovered radio waves, a milestone widely seen as confirmation of James Clerk Maxwell’s electromagnetic theory and which paved the way for numerous advances in communication technology. Born in Hamburg on February 22, 1857, Hertz was the eldest of five children.
For those who love science and radio (and who doesn’t), the German city of Karlsruhe should have a special place in their hearts. It was there that physicist Heinrich Hertz proved the existence of radio waves in the 1880s at a university now known as Karlsruhe Institute of Technology.
Heinrich Hertz was the first to send and receive radio waves. James Clerk Maxwell had mathematically predicted their existence in 1864. Between 1885 and 1889, as a professor of physics at Karlsruhe Polytechnic, he produced electromagnetic waves in the laboratory and measured their wavelength and velocity.
…was confirmed by German physicist Heinrich Hertz, who produced radio waves with sparks in 1887. With light understood as an electromagnetic wave, Maxwell’s theory could be applied to the emission of light from atoms. The theory failed, however, to describe spectral lines and the fact that atoms do not lose…
In a series of brilliant experiments Heinrich Hertz discovered radio waves and established that James Clerk Maxwell’s theory of electromagnetism is correct. Hertz also discovered the photoelectric effect, providing one of the first clues to the existence of the quantum world. ... Heinrich Rudolf Hertz died aged 36 in Bonn on January 1, 1894 ...
Heinrich Hertz Biography - biography of the life of Heinrich Hertz, the man who is credited with first knowingly demonstrating radio electromagnetic waves or Hertzian waves and radio communication. It is many years now since the name Hertz was adopted as the unit of frequency.
Interestingly, Heinrich Hertz did not think his experiments with electromagnetic radiation, particularly radio waves, had any practical value. His attention was focused solely on theoretical experiments. So, he proved that electromagnetic waves propagated through the air (and space).
