What is the max E that teh electron can obtain?

  1. Sep 27, 2011 #1
    A photon having 20 keV scatters from a free electron at rest. What is the maximum energy that the electron can obtain?



    2. Relevant equations
    [itex]\lambda[/itex]' - [itex]\lambda[/itex] = (h/mc)(1-cos(theta)


    3. The attempt at a solution
    i just dont know where to get started or anythign can someone show me how to do this?
