Today (June 21, 1957) is the Memorial Day of Nobel Prize-winning German physicist Johannes Stark, who discovered the Stark effect and the Doppler Effect.

  

Johannes Stark was born on April 15, 1874, in Germany. He also attended the Bareth Gymnasium (high school) in the German Empire Schickenhof and the school in Regensburg. He studied physics, mathematics, chemistry, and crystallography at the University of Munich. He then graduated in 1897. He received his doctorate in the field of research on certain physical and optical properties of heat. Became a volunteer lecturer at the University of Gottingen. In 1906 he became a professor at Hanover. In 1908 RWTH became a professor at Aachen University. Until 1922 he worked in the physics departments of several universities, including Creatvolt University.

 

There are electric currents in gases, spectroscopic analysis, and chemical values. He said his spectroscopic deals with the relationship between structure, structure, and the spectrum of chemical molecules. Doppler Effect detection in canal beams and splitting of spectral lines in electrical fields. In 1902 his book Electricity in Gases was published. This was followed by research on chemical molecules in the analysis of radiation molecules and electronic spectroscopy.

 

He authored a book, Chemical Atomic Electricity for Chemical Evaluation (Die Electricized Game of Thrones). Stark founded Jackboop der Reactivity and Electronic Reactivity and Electronics. In 1910 he received the Bombard Carter Prize from the Vienna Academy of Sciences and in 1914 the Cottonton Academy of Sciences Wallpooch Prize. He was awarded the 1919 Nobel Prize in Physics for his discovery of the spectral line splitting (Stark effect) in the electric field and his discovery of the Doppler Effect on canal rays.

 

The Stark effect is the presence of a luminous substance in an energetic electric field whose optical properties vary. This is also a part of spectral analysis. Similar to the Seaman effect. The magnetic field is used in response to the electric field during the seaman effect. The Doppler Effect is a change in the frequency of the wave for the observer moving according to the source of the wave. It is usually hearing the approach, passing, and mitigation of the viewer when a vehicle raises a horn or sound. Compared to the published frequency, the frequency obtained during access is higher, the frequency received during transit is equal, and the frequency received after passing is lower.

 

In recent years, Ebenstad, near his hometown of Transtein in Upper Bavaria, studied the effects of light diffraction in an irregular electric field. German physicist Johannes Stark passed away on June 21, 1957, at the age of 83 in Transstein, West Germany.
