Witryna1. Electrons & Photons. 2. 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. WitrynaHertz and Lenard’s Observations of the photoelectric effect This observation, which is connected to the photoelectric effect and how this effect is verified by two scientists, is one of Heinrich Hertz’s experiments in 1887 to prove the theory of electromagnetic light when he saw peculiar events when he placed two electrodes at a very tiny distance.
