Heinrich Rudolf Hertz was born in Hamburg Germany from Gustav Ferdinand Hertz and spouse Anna Elisabeth Pfefferkorn. He is the inventor of a physicist Hertz frequency. His father was a lawyer in Hamburg. While his mother was the daughter of an army doctor. While continuing his education at the University of Hamburg, he showed his intelligence in science as well as in language skills when learning Arabic and Sanskrit. He studied in Dresden, Munich and Berlin by two of his mentor, Gustav R. Kirchhoff and Hermann von Helmholtz.

He got a PhD in 1880 and became a disciple of Helmholtz samapai 1883. In 1885 he became professor at the University of Karlsruhe when researching an electromagnetic wave. Hertz became very interested in meeting with metorologi because Wilhelm von Bezold is a college professor when, following the practice of Hertz in Munich polytechnic. Even so, Hertz did not contribute much to the field except at the beginning masamasa when he became an assistant at Helmholtz in Berlin. Including studies of the evaporation of the liquid, the newest type of hygrometer, and an explanation of the charts with the state of adiabatic air.

At 1881-1882, Hertz published two articles, also known as the field of expert contacts. Hertz is known for his contributions in the field of dynamic electricity. Many papers that refer to the two articles as a source for some ideas. However, the Boussinesq magazine put out some criticism on the work of Hertz.


Around the 19th century, Maxwell expressed his equation which is quite surprising the world of Physics. One of them declared an electromagnetic wave. However, when it has not been proven. Karna, the Heinrich Hertz tried to prove the existence of electromagnetic waves.

In theory, electromagnetic waves Hertz realized that Maxwell stated a combination of electric waves and magnetic waves are mutually perpendicular. Similarly, the direction of motion. Because the wave mengantung electric waves, Hertz tried to prove the existence of electromagnetic waves through the existence of electrical waves radiated by the transmitter circuit.

Hertz tried to create with the help of a simple transmitter circuit to amplify the voltage transformer and capacitor as a container for cargo. Since there


current shift in the gap transmitter, there is expected to be radiation emitted electromagnetic waves. Because in theory, from the sparks that appear to be generated electromagnetic waves. As a result, the receiver circuit is just a loop-shaped wire loop that is given without any voltage source, it appears an electric spark in her gaps. This proves there is electricity flowing through a radiation benda.yang terhantarkan to the loop end.

Because it was not satisfied, Hertz tried to calculate the frequency of the loop. It turned out that the generated frequency equal to the frequency of the transmitter. This means that electricity comes from a transmitter on the loop itself. Is evident by the Maxwell electromagnetic wave radiation. Hertz experiment is also triggered the discovery of a wireless telegraph and radio by Marconi. This series is in the quartz glass to avoid UV rays.

In 1886, Hertz was able to prove the concept that very paradox that time, the Maxwell equations of electromagnetic waves. Even so, Einstein would later use these results to refute some of the concepts in classical physics of electromagnetic waves.

After that hertz continue his research. Until finally in 1887 Hertz experiment further proof of the results of electromagnetic waves. Until he finally got a pretty interesting fact accidental. Namely that the electric charge will be reduced if there are ultraviolet Sunar who fell between the two electrodes. That is the reason why Hertz using a quartz tube to prove Maxwell. At that time, Hertz did not pay attention to exactly what happened there. So there is no comprehensive research results and clear about the effect.


Hertz is the person who made a large contribution on the discovery of electromagnetic waves and the photoelectric effect. Though not intentionally, all kinds of proof has changed our world becomes more practical. Although eventually only a few know that the photoelectric effect was first discovered by Hertz. to appreciate the services of Heinrich Rudolf Hertz for his contribution in the field of electromagnetism named later immortalized as the unit of wave frequency (Hertz). Hertz (symbol: Hz) is the SI unit for frequency. Hertz stated the number of waves in one second (1 Hertz = 1 wave per second). This unit can be used to measure any periodic waveform. Example: The frequency of motion of a pendulum wall clock is 1 Hz.
