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 cobalt target (Z = 27) is bomberded with electron and the wavelength of its characteristic spectrum are measured . A second , fainter characcteristic spectrum is also found because of an impurity in the target. The wevelength of the K_(alpha) lines are 178.9 pm (cobalt) and 143.5 pm (impurity). What is the impurity?

A target element A is bombarded with electrons and the wavelengths of the characterstic spectrum are measured. A second characteristic spectrum is also obtained , because of an impurity in the target. The wavelengths of the K_(alpha) lines are 196 pm (element A) and 169 pm (impurity). If the atomic number of impurity is z=(10lambda-1) . Find the value of lambda . (atomic number of element A is 27).

From what meterial is the anod of an X-ray tube made if the K_alpha line wavelength of thej characteristic spectrum is 0.76 Å ?

From what meterial is the anod of an X-ray tube made if the K_alpha line wavelength of thej characteristic spectrum is 0.76 Å ?

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
