Energy of the Electron & Energy Levels

Let T1 and T2 be the energy of an electron in the first and second excited states of hydrogen atoms, respectively. According to the Bohr's model of an atom, the ratio T1: T2 is

Show answer and solution

Answer: (d)

First excited state is $n = 2$ , second excited state is $n = 3$ .
$E_n \propto \frac{1}{n^2}$ , so $\frac{T_1}{T_2} = \frac{1/4}{1/9} = \frac{9}{4}$
So the answer is (d) $9 : 4$ .
