Heinrich Rudolf Hertz (/ h ɜːr t s / HURTS; German: [ˈhaɪnʁɪç hɛʁts]; [1] [2] 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.
1887 experimental setup of Hertz's apparatus. 1886 to 1888: After noticing how discharging an electric current into a coil produced a spark in a second nearby coil, Heinrich Hertz sees a way to build a test apparatus to solve von Helmholtz "Berlin Prize" problem.
It is based on the photoelectric effect originally observed by Heinrich Hertz in 1887 and later explained by Albert Einstein in 1905 that when a material is shone by light, the electrons can absorb photons and escape from the material with the kinetic energy: =, where is the incident photon energy, the work function of the material.
German physicist Heinrich Hertz in 1887 built the first experimental spark gap transmitters during his historic experiments to demonstrate the existence of electromagnetic waves predicted by James Clerk Maxwell in 1864, in which he discovered radio waves, [23] [24]: p.3-4 [25] [17]: p.19, 260, 331–332 which were called "Hertzian waves" until ...
Heinrich Hertz. When German physicist Heinrich Rudolf Hertz was looking for a subject for his doctoral dissertation in ... 1887 experimental setup of Hertz's apparatus.
In 1887, Heinrich Hertz observed the photoelectric effect [27] and reported on the production and reception [28] of electromagnetic waves. [29] The receiver in his apparatus consisted of a coil with a spark gap, where a spark would be seen upon detection of electromagnetic waves. He placed the apparatus in a darkened box to see the spark better.

The experimental proof of Maxwell's equations was demonstrated by Heinrich Hertz in a series of experiments in the 1890s. [14] After that, Maxwell's equations were fully accepted by scientists. Relationships among electricity, magnetism, and the speed of light
