## ${\displaystyle n_{1}}$ and ${\displaystyle n_{2}}$

It would be very useful to have a description of what the numbers n1 and n2 mean physically. Just saying that the Balmer series, for example, is created by setting n1 equal to 2 and letting n2 run from 3 to infinity is all well and good, but it won't help someone understand what these numbers represent.

I've now added something more about that. Is that clearer? SBHarris 03:41, 16 January 2007 (UTC)
