Proceeding from Moseley's law find: (a) the wavelength of the \(K_{\alpha}\) line in aluminium and cobalt: (b) the difference in binding energies of \(K\) and \(L\) electrons in vanadium.

Reveal Answer
 (a) 843pm for Al,180pm for Co;(b)5keV . \text { (a) } 843 \mathrm{pm} \text { for } \mathrm{Al}, 180 \mathrm{pm} \text { for } \mathrm{Co} ;(\mathrm{b}) \approx 5 \mathrm{keV} \text { . }
