In equation form, this is given by KE e = hf − BE , where KE e is the maximum kinetic energy of the ejected electron, hf is the photon's energy, and BE is the binding energy of the electron to the particular material. (BE is sometimes called the work function of the material.)

The photoelectric effect is a phenomenon in which electrons are ejected from the surface of a metal when light is incident on it. |
Based on these findings, Einstein proposed that light behaved like a stream of particles called photons with an energy of E = h ν . |
Einstein figured out that it was the frequency of the light hitting the metal that was important. the formula E = hf. knock off the electrons. |
