Binding energy work function

WebNov 10, 2011 · The work function of a metal can be interpreted as the minimum bond energy or the bond energy of the surface electrons. If the energy of the incident photons is equal to the work function, the kinetic energy of the released electrons will be zero. What is the difference between Work Function and Threshold Frequency? WebThe work function (binding energy) is the energy that must be supplied to cause the release of an electron from a photoelectric material. The corresponding photon frequency is the threshold frequency. The higher the energy of the incident light, the more kinetic energy the electrons have in moving away from the surface. ...
