Question:
You want to give an electron an evergy of 25kev in a Compton Collision. What is the minimum initial photon energy you need?
Equations:
[tex]\Delta[/tex][tex]\lambda[/tex]= h/mec(1-cos([tex]\theta[/tex]))
E=mc2
E=hv=hc/[tex]\lambda[/tex]
I'm not really sure where to start from here. I know the answer is 138kev but I am not sure how to go about getting it.
