Question
When an excited hydrogen atom returned to its ground state, some visible quanta were observed along with other quanta. Which of the following transitions must have occurred?
Options
A.2 → 1
B.3 → 1
C.3 → 2
D.4 → 2
Solution
Since some visible quanta were observed along with other quanta, electrons must have made transition from some higher state to n = 2 and then from n = 2 to n = 1
∴ Transition from 2 → 1 is compulsory, because electron from n = 2 will finally fall into n = 1.
∴ Transition from 2 → 1 is compulsory, because electron from n = 2 will finally fall into n = 1.
