Vedclass · Answer

(C) The energy of a characteristic $X$-ray photon is given by $E = \frac{hc}{\lambda}$.For the $K$-series,the transitions are from higher shells to the $K$-shell $(n=1)$.The energy levels are $E(K_{\alpha}) Since $E = \frac{hc}{\lambda}$,energy and wavelength are inversely proportional.Therefore,$E(K_{\gamma}) > E(K_{\beta}) > E(K_{\alpha})$ implies $\lambda(K_{\gamma}) < \lambda(K_{\beta}) < \lambda(K_{\alpha})$.
