Question

find the energy of an x-ray photon which can impact a maximum energy of 50 kev to an electron

Answer 1

Find the energy of x _ray photon which can impart a maximum energy of 50 Kev to an electron.

Answer 2

KE = h(nu_i - nu_f) but for maximum transfer of energy nu_f = 0.5*nu_i.
So answer will be 100 keV.
