Photoelectric effect (Hertz & Lenard’s Observations) • Discovered in 1887 by Heinrich Hertz. • The phenomenon of emission of electrons by certain substance (metal), when it is exposed to radiations of suitable frequencies is called as photoelectric effect and emitted electrons are called photoelectrons. 3. 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 …

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 … WitrynaWhile Hertz and Lenard hold that the cathode rays are vibrations in the ether or even light of short wave-length, Crookes and J; J. Thomson have urged that the rays are negatively charged matter traveling with great velocity. M. Per-rin reported to the Paris Academy, on December 30th, experiments which tend to show that the

Thomson in 1897 and W. Wien in 1897, which proved the corpuscular nature of the cathode rays.
