Transitions, Photon Emission & Excitation

The minimum energy required by a hydrogen atom in ground state to emit radiation in Balmer series is nearly:

Show answer and solution

Answer: (c)

Balmer lines end on $n = 2$ , so the atom must first reach at least $n = 3$ .
Minimum energy $= 13.6\left(1 - \frac{1}{9}\right) = 12.09$ eV
So the answer is (c) $\approx 12.1$ eV.
