THE PHOTOELECTRIC EFFECT
... THEORY: When light (or other electromagnetic radiation) is incident on a metal surface, electrons can be released from the metal. This is the photoelectric effect. According to classical theory, the electrons are shaken loose from atoms by the electric field of the incident light, and so a brighter ...

... Does light act as photons (“particles” or “quanta” or “packages”)? • An increase in intensity of light means more photons are incident, so more electrons will be ejected (more electrons means more current flowing); but since the energy of each photon is the same, the max KE of the electrons is not ...
