if the ionisation energy of hydrogen atom is 136ev the

If the ionisation energy of hydrogen atom is 13.6$$\,eV,$$ the energy required to excite it from ground state to the next higher state is approximately

A. 3.4$$\,eV$$

B. 10.2$$\,eV$$

C. 17.2$$\,eV$$

D. 13.6$$\,eV$$

Answer : 3.4$$\,eV$$

Solution :
$${E_n} = \frac{{ - {E_1}}}{{{n^2}}};$$ $${E_1} = 13.6;{E_{{n_2}}} = \frac{{13.6}}{4} = 3.4\,eV$$
