The graph between the square root of the frequency of a specific line of characteristic spectrum of X - rays and the atomic number of the target will be

(A) atoms of each element are stable and emit characteristic spectrum. (R) the spectrum provides useful information about the atomic structure.

A cobalt (atomic no. =27 ) target is bombereded with electrons and the wavelength of its characteristic x -rays spectrum are measured. A seconf weak characteristic spectrum is also found due to an impurity in the target. The wavelength of the K_(alpha) lines 225.0pm (cobalt ) and 100.0pm (impurity). Atomic number of the impurity is (take b=1)

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
