Homework Statement
What is the minimum energy that photons must have to produce 25 keV electrons in a Compton scattering? (answer in keV)
Homework Equations
Not too sure here, We know Eincident= Efinal + K.E.electron
We know that the work function (binding energy) is also taken into account but most of the time it is in eV, so we can (i think) omit that here.
The Attempt at a Solution
Not sure once again. How can we find the minimum incident energy of a photon without any other info but the 25 K.E. of the electron.
My logic tells me that, why can't it be 26 keV, Efinal = 1kev and KE of electron = 25 kev.
Help please Thanks
