and [edit]

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)

An obvious mathematical mistake in this article[edit]

"Rydberg rewrote this in terms of wavenumbers as n = no − 4no/m ².

"This shows that hydrogen is a special case with m = 0 and C0=4no. Co is a universal constant common to all elements."

This immediately gives division by zero in the first line when m = 0 from the second line is substituted in.

My master's degrees are in electrical engineering and mathematics, and I don't remember enough from my long Modern Physics course to correct the expressions here.74.249.82.7 (talk) 03:21, 18 September 2008 (UTC)

I added a prime-sign, it is m-prime in the formula before that is zero. Thank you for pointing this out. /Pieter Kuiper (talk) 11:39, 11 October 2008 (UTC)
