In the Bohr atom model, the frequency of transitions is given by the following expression
v = `"Rc" (1/"n"^2 - 1/"m"^2)`, where n < m
Consider the following transitions:
| Transitions | m → n |
| 1 | 3 → 2 |
| 2 | 2 → 1 |
| 3 | 3 → 1 |
Show that the frequency of these transitions obey sum rule (which is known as Ritz combination principle).
