Vedclass · Answer

(D) Characteristic $X-$ rays are produced when a high-energy incident electron knocks out an inner-shell electron (e.g.,from the $K$ shell) of the target atom.This creates a vacancy in the inner shell,making the atom unstable.An electron from a higher energy level (e.g.,the $L$ shell) then drops down to fill this vacancy.The energy difference between these two shells is released in the form of a photon,which constitutes the characteristic $X-$ ray.Therefore,the energy of the photon comes from the electronic transition within the target atom.
