WebSample Learning Goals. Visualize and describe the photoelectric effect experiment. Correctly predict the results of experiments of the photoelectric effect: e.g. how changing the intensity of light will affect the current and the energy of electrons, how changing the wavelength of light will affect the current and the energy of electrons, how ... WebThe photoelectric effect is the phenomena in which electrons are emitted from the surface of a metal upon the absorption of electromagnetic radiation. Electrons removed from a metal in this manner are known as photoelectrons. The photoelectric effect provides important evidence that light is quantised, or carried in discrete packets.
