How many emission spectral lines are possible when hydrogen atom is excited to \(n\)th energy level?
- A \(\frac{n(n+1)}{2}\)
- B \(\frac{(n+1)}{2}\)
- C \(\frac{(n-1) n}{2}\)
- D \(\frac{n^2}{4}\)
Answer & Solution
Correct Answer
(C) \(\frac{(n-1) n}{2}\)
Step-by-step Solution
Detailed explanation
Number of spectral lines \(=\frac{n(n-1)}{2}\) \(n\) is the orbital in which the electron exist.
