Electrons absorbed from a photon can only be in discrete amount and match the energy difference between different energy level. However, in photoelectric effect a photon can ionize an electron and give K.E. to the electrons. As K.E. can be any arbitrary amount instead of discrete, does it mean that any photon with energy greater than the ionizing energy can be absorbed by an electron in any arbitrary amount (all the excess energy becomes K.E. of electron)?
