Question

Which of the following describes the maximum energy of a photoelectron?

A. The maximum energy of a photoelectron is always the same as the energy of the incident photon.

B. The maximum energy of a photoelectron cannot be greater than the energy of the incident photon plus the minimum energy needed to escape from the surface of the metal.

C. The maximum energy of a photoelectron cannot be greater than the energy of the incident photon minus the minimum energy needed to escape from the surface of the metal.

D. The maximum energy of a photoelectron is less than the work function of the metal.

Answer 1

C. The maximum energy of a photoelectron cannot be greater than the energy of the incident photon minus the minimum energy needed to escape from the surface of the metal.
