Question 102: Atoms & Nuclei

Question

The number of spectral lines emitted by atomic hydrogen that is in the 4th energy level, is

Accepted Answer

When an e transition from n$^{th}$ to ground state then $$\sum {(n - 1)} $$ spectral lines are produced.
Given, $n=4$
So, $$\sum {(4 - 1) = \sum {3 = 3 + 2 + 1 = 6} } $$
Hence, 6 spectral lines are emitted by atomic Hydrogen that is in the $4^{th}$ energy level
