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. Philipp Lenard in 1902 demonstrated that illuminating a metal surface liberated …

WitrynaHeinrich Rudolf Hertz (/ h ɜːr t s / HURTS; German: [ˈhaɪnʁɪç ˈhɛʁts]; 22 February 1857 – 1 January 1894) was a German physicist who first conclusively proved the existence of the electromagnetic waves … Witryna12 wrz 2024 · The photoelectric effect has three important characteristics that cannot be explained by classical physics: (1) the absence of a lag time, (2) the independence of the kinetic energy of photoelectrons on the intensity of incident radiation, and (3) the presence of a cut-off frequency. Let’s examine each of these characteristics.

WitrynaThis effect originally was discovered actually by Hertz in 1887. It's now called the photoelectric effect, but originally it was actually called the Hertz effect. So here I present a schematic of Lenard's experiment copied from his original paper published back in 1902, that is the year here.
WitrynaEinstein noted that careful experiments involving the photoelectric effect could show whether light consistes of particles or waves. In 1887, German physicist Heinrich Hertz noticed that shining a beam of ultraviolet light onto a metal plate could cause it to shoot sparks.
