Textbooks say that by measuring the stopping potential V0, we can determine the maximum kinetic energy with which electrons leave the cathode: eV0 = Kmax
However, as I know, when we apply the stopping potential, the electrons will decelerate and radiate parts of their energies. Thus, the stopping potential measured V will be less than V0 in the equation above.
Could anyone please explain this problem?
Thank you very much.
