(B) In an atom,the energy levels are defined such that the energy of the $K_{\beta}$ transition is equal to the sum of the energies of the $K_{\alpha}$ and $L_{\alpha}$ transitions.Since the energy of a photon is given by $E = h\nu$,we have:$E(K_{\beta}) = E(K_{\alpha}) + E(L_{\alpha})$Substituting the frequency relations:$h\nu_2 = h\nu_1 + h\nu_3$Dividing by $h$,we get:$\nu_2 = \nu_1 + \nu_3$
