Philipp Lenard. Philipp Eduard Anton von Lénárd ( 7 tháng 6 năm 1862 ở Pressburg (ngày nay là Bratislava ), Áo-Hung – 20 tháng 5 năm 1947 ở Messelhausen, Đức) là một nhà vật lý học người Hung-Đức đoạt giải Nobel Vật lý năm 1905 nhờ những nghiên cứu về tia âm cực và khám phá nhiều đặc ...
These aspects are (1) Lenard's trigger hypothesis to explain the photoelectric effect, (2) Einstein's quantum hypothesis to explain the photoelectric effect, (3) lack of acceptance of Einstein's quantum hypothesis in the scientific community, (4) Millikan's experimental determination of the Einstein photoelectric equation and Planck's constant, h, (5) Millikan's presuppositions about the ...
Philipp Eduard Anton von Lenard (1862–1947) war ein erfolgreicher und brillanter Physiker. Er erhielt 1905 den Nobelpreis für Physik, nachdem er neue Entdeckungen über Kathodenstrahlen gemacht hatte, welche die bestehenden Theorien über deren Eigenschaften korrigierten. Lenard war allerdings auch ein Antisemit und glühender Nationalist ...

Más tarde, Lenard amplió los trabajos de Hertz sobre el efecto fotoeléctrico, demostrando que cuando la luz ultravioleta incide en el vacío sobre ciertos metales arranca electrones del metal. Estos electrones se propagan en el vacío pudiendo ser acelerados o retardados por un campo eléctrico, y sus trayectorias se pueden curvar por un campo magnético.
A Nobel winner’s descent. Stories from Physics for 11-14 14-16 16-19. Philipp Lenard had been an assistant of Hertz and built on his work on the photoelectric effect. He discovered that the total charge of electrons emitted, but not their velocity, depended on the intensity of light shone on to the metallic surface.
23 de may. de 2018 · Philipp Lenard. German physicist Philipp Lenard (1862–1947) won the 1905 Nobel Prize for his research into the properties of cathode rays. His reputation was later tarnished, however, thanks to his support of Germany's National Socialist (Nazi) Party and its racial–superiority theories.
