WebThis phenomenon is called the photoelectric effect. Heinrich Hertz, a German physicist, discovered the photoelectric effect in 1887. 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.
