Hertz and lenard's observations

Witryna29 lut 2024 · Hertz and Lenard's observations in the photoelectric effect are as follows. 1. Hertz observed the photoelectric effect and the production and reception of electromagnetic waves. 2. Lenard observed that if light frequency varies then electron energy also varies, using a powerful electric arc lamp which enabled him to … WitrynaHeinrich Hertz, a German physicist, discovered the photoelectric effect in 1887. He observed that shining an ultraviolet light on electrodes caused a change in the voltage between them. Other work during the 19th century built on Hertz’s observations.

Witryna18 lut 2024 · Einstein's explanation of the photoelectric effect built upon experimental data gathered by Heinrich Hertz, who was the first to observe the effect, as well as J. J. Thomson and Philipp Lenard. WitrynaIn connection with work on radio waves, Hertz observed that, when ultraviolet light shines on two metal electrodes with a voltage applied across them, the light changes the voltage at which sparking takes place. This relation between light and electricity (hence photoelectric) was clarified in 1902 by another German physicist, Philipp Lenard.
