Ray optics introduction

Which of the following is accompanied by the characteristic X - ray emission ?

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 the
