Electrons are excited from \(n=1\) to \(n=4\) state. During downward transitions, possible number of spectral lines observed in Balmer series is
- A 4
- B 3
- C 2
- D 1
Answer & Solution
Correct Answer
(C) 2
Step-by-step Solution
Detailed explanation
In Balmer series, the electrons moves to \(n=2\) state So, possible transitions are \(4 \rightarrow 2,3 \rightarrow 2\). \(\therefore\) Number of spectral lines are 2 .
