This is more of a conceptual question.
--------------------
1.[tex]KE_{Max} = hf-\phi[/tex]
2.[tex]\phi[/tex] = Work Function. The minimum energy required to free an electron with a photon
3.[tex]E=hf[/tex] This it the energy of a photon
---------------------
In my book it says that" [tex]hf > \phi[/tex]" then electrons can be ejected" and ""If the light frequency is too low, such that the photon energy [tex]hf[/tex] is less than the work function [tex]\phi[/tex], then there is simply insufficeient energy in any given photon to free an electron.
What is the kinetic energy of an electron if the energy of a photon is the same as the Work Function? Like what happens?
