While a particular metal is illuminated with photons, one electron is practical for each absorbed photon. Explain what effect would increase the energy and numbers of photons have on electrons leaving the surface?
1- There would be more electrons
2- The electron velocity would be lower
3- The kinetic energy of electrons would be lower
4- Two photons may be required to eject the electrons
5- They would have higher kinetic energy
