I was playing around with this PheT simulation: https://phet.colorado.edu/en/simulation/photoelectric
Under a certain threshold wavelength and an intensity at 20%, the electrons were being emitted from the Sodium surface. Without changing anything, the elctrons did not share the same velocity. Why?
Right now, I am under the assumption that the atoms in which the electrons are emitted from are all the same in terms of energy level configuration. For example, in order for an electron to jump from n=1 to n=2 it would require a photon containing 3eV (making it up btw) of energy, the electron ignores all photons containing a different amount of energy.
Now, also under the assumption that the frequency of the incoming photon packets remains constant throughout, wouldn't it make sense for the emitted electrons to be all traveling at the same velocity?
TL;DR: If an electron requires a discrete amount of energy to jump, and if photon packets are shone at a metal surface without changing the frequency(they all have the same energy), why do some electrons travel faster than others when emitted as if they were able to receive more energy?
