PART I: The Photoelectric Effect
When light (EM radiation) of sufficiently high frequency is incident on the surface of a metal, electrons can be knocked from the surface. This is the photoelectric effect.
The photoelectric effect supports the particle theory for light. The energy of an incident photon is transferred with some of the energy going into the work done to eject the electron from the surface (the work function) and the remaining energy converting to the kinetic energy of the ejected electron. You can get a copy of the Photoelectric Effect booklet that we have been using in class from the the Year 13 Physics Google Classroom.
