Einstein's description of the photoelectric effect, also known as photoionization, laid the theoretical foundation for quantum mechanics. However, the instantaneous nature of this effect has been ...

This observation was first made by Philipp Lenard, who did initial work on the photoelectric effect. In order to explain this, in 1905, Einstein suggested in Annalen der Physik that light ...

Albert Einstein, best known for his work in relativity, won the Nobel Prize for his formula for the photoelectric effect, which often surprises modern physicists.

I took a deep dive into the photoelectric effect — where light hits a surface and kicks electrons out. It’s simple, ...
