The photoelectric effect, discovered by Heinrich Hertz in 1887, involves the emission of electrons from a metal surface when illuminated by ultraviolet light. Key observations include a linear relationship between stopping potential and frequency of incident radiation, and the existence of a minimum cut-off frequency below which no emission occurs. Additionally, the maximum kinetic energy of emitted photoelectrons is dependent on frequency but not on intensity.
