Phenol gives characteristic colouration with

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)

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

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
