### Question 1.11

In the spectrum of atomic hydrogen, several lines are generally classified 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?

The answers say that each series has a different lower energy level, but what does the "lower energy level" mean in this context? Isn't the lower energy level n=1?

### Re: Question 1.11

they start off in the same energy level so that is why grouping them is logical

### Re: Question 1.11

The lower energy level in this context is referring to the level that each series starts at. UV light corresponds to n=1, visible light corresponds to n=2, and infrared light corresponds to n=3. When you do problems with the different series, when they say "lower energy level", you must assess what type of light it is and then decided what your lowest n value can be.
