Consider a beam of electrons (each electron with energy E0) incident on a metal surface kept in an evacuated chamber. Then
- no electrons will be emitted as only photons can emit electrons.
- electrons can be emitted but all with an energy E0.
- electrons can be emitted with any energy, with a maximum of E0 – f (f is the work function).
- electrons can be emitted with any energy, with a maximum of E0.
Answer
(C) electrons can be emitted with any energy, with a maximum of E 0 – f ( f is the work function).
