Question
In a sample of hydrogen atoms, all the atoms are in a particular excited state. If the emission spectrum of this sample has only 4 spectral lines in the visible region, then the total number of spectral lines in IR region possible from that state is
Options
A.6
B.5
C.7
D.15
Solution
Excited state is n = 6 [3 → 2, 4 → 2, 5 → 2, 6 → 2]
∴ Number of spectral lines in 1R region = 6.
