Help photoelectric effect

    Help!!!photoelectric effect

    Hi guys, for an electron to jump from a lower energy to a higher energy state, it must absorb photons that correspond to the difference of the these 2 enegry states. I am wondering if it is okey for an electron to absorb greater frequency of photons(greater energy) to make the transition and release the extra energy?

    Yes... as long as it is enough energy to get right out from the atom. The electron gets ejected with a velocity that makes up the energy difference. But for less than the ionization energy, you are pretty much limited to the transitions from one level to another.
