Physics/Bohr model vs photoelectric / Compton effect

Question
How can I relate Bohrs theory of excited electrons to compton's scattering and the photoelectric effect? Does Bohr's model define what happens when a frequency less than the threshold one interacts with an electron?
Please advise!

Answer
Dear Kai;

First, sorry for the delay getting back with you.

To your first question:
The Bohr model predicts the photoelectric effect but does not predict Compton scattering.

To your second question:
Since the Bohr model uses photons as purely wave-like entities, there is no room in that model for photon's which do not meet the energy requirements of a transition.  For Compton scattering to be accounted for, one must assume a particle-like character as well as wave-like character.  Only then can one discuss the system in terms of momentum conservation and mass-energy conservation.

Synopsis: Because the Bohr model assumes only wave-like properties in photons, Compton scattering cannot be predicted by it.
