A beam of electrons striking a cooper target produces X-rays. Its spectrum is as shown. Keeping the voltage same if the copper target is replaced with a different metal, the cut-off wavelength and characteristic lines of the new spectrum will change in comparison with old as:

A

Cut off wavelength will remain unchanged while characteristic lines will be different.

B

Both cut-off wavelength and characteristic lines will remain unchanged.

C

Both cut-off wavelength and characteristic lines will be different.

D

Cut -off wavelength will be different while characteristic lines will remain unchanged.

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
