An electron makes a transition from orbit n = 4 to the orbit n = 2 of a hydrogen atom. What is the wavelength of the emitted radiations? (R = Rydberg constants) |
$\frac{16}{4R}$ $\frac{16}{5R}$ $\frac{16}{2R}$ $\frac{16}{3R}$ |
$\frac{16}{3R}$ |
The correct answer is Option (4) → $\frac{16}{3R}$ |
