Heinrich Rudolf Hertz was a German physicist responsible for discovering how to produce electromagnetic waves.
Heinrich Rudolf Hertz was a German physicist who was born on February 22, 1857, in Hamburg. During his basic study he was always interested in science, and this interest led him to join the Faculty of Physics at the University of Berlin in 1878. In 1880, Hertz became an assistant to Professor von Helmholtz, carrying out studies on elasticity and the electrical energy transmission capacity of gases .
In 1883, Hertz became a professor at the University of Kiel, where he went on to develop studies on Maxwell’s electrodynamics . In the year 1885, he moved to Karlsruhe, where he taught at the Polytechnic School.
When carrying out experiments with coils connected to sparklers, Hertz realized that when one of the coils released a spark, the other also released an electrical spark of less intensity and luminosity. Then, the scientist understood, after repeating the experiment several times, that the secondary sparks were the product of the propagation of electromagnetic waves .
