### Solving 1.11

1.11 In the spectrum of atomic hydrogen, several lines are generally classi ed together as belonging to a series (for example, Balmer series, Lyman series, Paschen series), as shown in Figs. 1.10 and 2.1. What is common to the lines within a series that makes grouping them together logical?
What would be a proper explanation for the grouping principle?

Grouping these waves into series is helpful because it allows the waves to be categorized by energy levels. i.e Lyman's series are all ultraviolet, Paschen's lie in infrared.

The final state which ends up is different for the series that are named. Lyman ends in n =1 for example.

### Re: Solving 1.11  [ENDORSED]

I agree with these responses, but another way to put it is that the principal quantum number is the same for each of these lines, so Lyman- n=1, Balmer- n=2, etc.
