Lecture 25 : Reason for the unshifted peak in the spectrum
  Thus the final momentum of the electron is $ 1.105\times 10^{-22}\hat\imath -7.9\times 10^{-23}\hat\jmath$. The angle that the final direction of electron makes with the x-axis is
 
The change in the energy of the electron is negative of the change in the energy of the photon which is
 
$ (hc/\lambda_0 - hc/\lambda) = 9.47\times 10^{-15}\ J = 59.2$ keV.
