Photon-Electron Collision

[AKG]

If I'm given an energy for an electron, and a wavelength for a photon, how can I determine the maximum energy loss for the electron?

You can convert wavelength to energy (E) and work from there. The equations you need are:

E=hf, where h= Planck's constant and f= frequency.
c=wf, where w= wavelength and c= speed of light.
