Hey guys, I have a final tomorrow and I am going over some assignments. One of the questions from the assignment was:
A photon having 37 keV scatters from a free electron at rest. What is the maximum energy that the electron can obtain?
Now, I got the right answer (4.67 KeV) but I can't seem to figure it out now. Maybe I am just too tired. Any hints to where I should begin?
