Eugen Goldstein
German physicist
Eugen Goldstein (OY-gən, German:[ˈɔʏɡeːnˈɡɔlt.ʃtaɪn,ˈɔʏɡn̩-]; 5 September &#; 25 December ) was a German physicist. He was an early investigator of discharge tubes, the discoverer of anode rays or canal rays, later identified as positive ions in the gas phase including the hydrogen ion.[1][2] He was the great uncle of the violinists Mikhail Goldstein and Boris Goldstein.
Life
[edit]Goldstein was born in at Gleiwitz Upper Silesia, now known as Gliwice, Poland, to a Jewish family. He studied at Breslau and later, under Helmholtz, in Berlin. Goldstein worked at the Berlin Observatory from to but spent most of his career at the Potsdam Observatory, where he became head of the astrophysical section in He died in and was buried in the Weißensee Cemetery in Berlin.
Work
[edit]In the mid-nineteenth century, Julius Plücker investigated the light emitted in discharge tubes (Crookes tubes) and the influence of magne

Canal Ray Experiment
Q1
Who discovered the canal rays?
Dempster was one of the first spectrometers to use such sources of ions. He never succeeded in using magnetic bending. By the light, they released while travelling through gases and by the fluorescent patch they created on the discharge tube wall, Goldstein had discovered canal rays.
Q2
Why anode rays are called canal rays?
These rays are particle beams that travel in a direction opposite to the “cathode rays,” which are electron waves that move through the anode. These were called canal rays because they passed through the holes or canals in the cathode
Q3
What was Goldstein experiment?
In the s, Goldstein conducted his own discharge tube experiments and named Kathodenstrahlen, or cathode rays, the light emissions examined by others. He funnen some major cathode ray properties, which led to their subsequent discovery as the electron, the first subatomic particle.
