Conclusion. Hence initially, the photoelectric effect was discovered by Hertz and Lenard; it could not do justice to the equation given by Planck. The explanation given by Einstein helped clearly define the ...
WitrynaHeinrich 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.
