Abstract	In deducing the change of wavelength of x-rays scattered by atomic electrons, one normally makes use of relativistic kinematics for electrons. However, recoiling energies of the electrons are of the order of a few keV which is less than 0.2% of their rest energies. Hence the authors may ask whether relativistic formulae are really necessary. In this article, they derive the formula for the change in wavelength of x-rays using non-relativistic kinematics for electrons. It so happens, by some coincidence, that relativistic kinematics leads to exact simplification of the equations. Perhaps that is the reason for its use rather than physical considerations.
