Transitions, Photon Emission & Excitation

The ratio of energies of photons produced due to transition of electron of hydrogen atom from its (i) second to first energy level and (ii) highest energy level to second energy level is

Show answer and solution

Answer: (b)

$E \propto \left(\frac{1}{n_f^2}-\frac{1}{n_i^2}\right)$
$2\to1$ : $1-\frac14 = \frac34$ . $\infty\to2$ : $\frac14$ .
Ratio $= \frac34 : \frac14 = 3:1$
So the answer is (b) $3:1$ .
