James Franck. geb. 1882 in Hamburg. gest. 1964 in Göttingen. Gustav Hertz. geb. 1887 in Hamburg. gest. 1975 in Ostberlin. Um 1914 (also ein Jahr nachdem Bohr sein Modell formuliert hatte) beschäftigten sich viele Physiker mit Gasentladungen (In ein Gas - meist mit Unterdruck - werden zwei Elektroden eingebracht, an die eine Spannung angelegt ...
1. Juni 2010 · James Franck was one of Germany’s leading experimental physicists in the 1920s and early 1930s. He is remembered by physicists today primarily because of the Franck-Hertz experiment, for which he and Gustav Hertz were awarded the 1925 Nobel Prize in Physics, and for the Franck-Condon principle. Franck left Germany in 1933. As an immigrant in the US, he resumed his earlier efforts to ...
James Franck was a German-American physicist born on August 26, 1882 in Hamburg, Germany. He received the Nobel Prize for physics in 1925 for his research on the interaction of electrons and atoms. Franck attended school in Hamburg where most of his classes focused on the classics and languages but failed to hold his interest.
4. Aug. 2011 · James Franck studied in Berlin and was awarded his doctorate there under Emil Warburg; he qualified as a professor in 1911. This was the time when his collaboration began with Gustav Hertz at the Institute of Physics of Friedrich-Wilhelms-Universität. It led to a spectacular result after only two years of research. The physicists conducted impact tests with electrons and atoms in 1913. They ...
James Franck was born in Hamburg, Germany, on August 26, 1882. He completed his Ph.D. in physics in 1906 at the University of Berlin, where he would shortly rise to the rank of associate professor of physics. With the onset of the First World War, he volunteered for the army as a private. He was wounded, received the iron cross, and eventually ...
Eine Elektronenstoßröhre im Franck-Hertz-Versuchs im physikalischen Praktikum. C = Kathode, G = Gitter, A = Auffänger. Als Franck-Hertz-Versuch wird das vorletzte Glied einer dreijährigen Serie von Experimenten bezeichnet, mit denen James Franck und Gustav Hertz untersuchten, wie viel Energie von einem Elektron bei einem Stoß mit einem Atom auf dieses übertragen wird.
James Franck (26 tháng 8 năm 1882 – 21 tháng 5 năm 1964) là một nhà vật lý người Đức. James Franck và Gustav Ludwig Hertz đã chứng minh hiệu ứng quang điện ngược (tức là khi một điện tử va chạm với một nguyên tử thì cần một năng lượng tối thiểu để sinh ra các lượng tử ánh sáng với năng lượng đặc trưng phát ...
