Ionisation energy of H-atom$=13.6\mathrm{ }\mathrm{e}\mathrm{V}$

$\therefore \mathrm{h}{f}_{\mathrm{m}\mathrm{i}\mathrm{n}}=13.6\mathrm{ }\mathrm{e}\mathrm{V}$

$\therefore f_{\mathrm{m}\mathrm{i}\mathrm{n}}=\frac{13.6\times 1.6\times {10}^{-19}}{6.63\times {10}^{-34}}=3.28\times {10}^{15}\mathrm{ }\mathrm{H}\mathrm{z}$
