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

    An electron beam is acceleration by a potential difference V to hit a metallic target to produce X-rays. It produces continuous as well as characteristic X-rays. If lambda_(min) is the smallest possible wavelength of X-rays in the spectrum, the variation of log lambda_(min) with log v is correctly represented in

    Electrons with de-Broglie wavelength lambda fall on the target in an X-ray tube. The cut-off wavelength of the emitted X-ray is

    If Z is the atomic number of the target atom, then the frequency of the K_alpha line of the characteristic X ray spectrum is directly proportional to

    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
