WebbThe photoelectric effect would be a key to demonstrating Einstein’s brilliance. Consider the following five properties of the photoelectric effect. All of these properties are consistent with the idea that individual photons of EM radiation are absorbed by individual electrons in a material, with the electron gaining the photon’s energy. Webbphotoelectric: [adjective] involving, relating to, or utilizing any of various electrical effects due to the interaction of radiation (such as light) with matter.
