WitrynaIn 1902, Lenard observed that the kinetic energy of electrons emitted increased with the frequency of radiation used. This could not be explained as Maxwell’s electromagnetic theory (which Hertz proved … WitrynaHertz did not follow up on these observations. J. J. Thomson – 1889 . ... Philipp Lenard – 1902 . Philipp Lenard was a student of Heinrich Hertz. Lenard began studying cathode rays in 1888 and in the process replicated some of Thomson’s experimental work. By 1902, Lenard had done various experiments manipulating different light ...

Lenard and Hallwachs experimented on the phenomenon of photoelectric emission between the years 1886 … WitrynaThese orbits prove Plank’s observations that atoms absorb or emit electromagnetic radiation in certain units, known as quanta. Conclusion. Hence initially, the photoelectric effect was discovered by Hertz and Lenard; it could not do justice to the equation given by Planck. The explanation given by Einstein helped clearly define the ...

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.
