X-rays emitted from a copper target and a molybdenum target are found to contains a line of wavelength 22.85nm attributed to the K_(alpha) line of an impurity element. The K_(alpha) lines of a copper (Z=29) and molybdenum (Z=42) have wavelength 15.42nm and 7.12nm respectively. Using Moseley's law, gamma^(1//2)=a(Z-b) . Calculate the atomic number of the impurity element.
