### Re: 1.11 Problem

In each of these series, the principal quantum number for the lower energy level involved is the same for each absorption line. Thus, for the Lyman Series, the lower energy level is n=1; for the Balmer series, n=2; for the Paschen Series, n=3; and for the Brackett series, n=4.

### Re: 1.11 Problem

Would the answer still be correct if I said that they pertain to different parts of the spectrum like how the Balmer series pertains to visible light while the Lyman series regards UV radiation? Or does the answer have to mention the lower energy levels to be right?

### Re: 1.11 Problem

I believe that the part about the lower energy levels is shown on the solutions manual, but ultimately I think this whole thing about the energy level is what leads to the series being categorized as they are,i.e. that the Balmer series is in the visible light region and the Lyman series in the UV region.
