Lenard was the first to cause cathode rays to pass from the interior of a vacuum tube through a thin metal window into the air, where they produce luminosity. Lenard received the 1905 Nobel Prize in Physics for his research in this field. He is noted also for his work on the structure of the atom and for the discovery in 1902, in connection with the photoelectric effect, that the velocity of ...

photoelectric current was not clear and led to considerable controversy. Philipp Lenard’s Triggering Hypothesis Lenard (1902) was an acknowledged expert on cathode rays and generally agreed with Hertz (with whom he had worked as an assistant) that both cathode rays and x-rays were
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.

Heinrich Hertz and Philipp Lenard made important contributions to the phenomenon of the photoelectric effect. Lenard found that there was a defined and proper minimum voltage that stopped any electron from getting through (Vstop). However, to his surprise, Lenard discovered that Vstop did not depend upon the intensity of light. When the light ...
