Consider a beam of electrons (each electron with energy \( E_{0} \) ) incident on a metal surface kept in an
\( \mathrm{P} \)
evacuated chamber. Then,
W
(1) no electrons will be emitted as only photons can emit electrons
(2) electrons can be emitted but all with an energy, \( E_{0} \)
(3) electrons can be emitted with any energy, with a maximum of \( E_{0}-\phi \)
( \( \phi \) is the work function)
(4) electrons can be emitted with any energy, with a maximum of \( E_{0} \)
