Transitions, Photon Emission & Excitation

According to Bohr atomic model, in which of the following transitions will the frequency be maximum?

Show answer and solution

Answer: (a)

$\nu \propto \left(\frac{1}{n_f^2}-\frac{1}{n_i^2}\right)$ ; the gap is largest for the lowest levels.
$2\to1$ : $0.75$ ; $3\to2$ : $0.139$ ; $4\to3$ : $0.049$ ; $5\to4$ : $0.023$
So the answer is (a) $n=2$ to $n=1$ .
