When high energetic electron beam , (i.e., cathode rays) strike the heavier metal, then X-ray are produced. Spectrum of X-ray are classified into two categories: (i) continous spectrum, and (ii) characteristic depends only on the potential difference across the electrode. But wavelength of characteristic spectrum depends on the atomic number `(z)`. The production of characteristic X-ray is due to theA. continuous acceleration of incident electrons towards the nucleusB. continuous ratardation of incident electrons towards the nucleusC. electron transition between inner shells of the target atomD. electron transition between outer shells of the target atom
