[SOLVED] Photon emissions from hydrogen

Homework Statement

How many different photon emissions can hydrogen atom make going down from excited state 5 to ground level ?

Homework Equations

Thats what I'm lookin for.

The Attempt at a Solution

Simply by counting I got 10 different photon emissions.
But is there some equation for doing this elegantly ?

you have, of course. tried google with a bunch of terms like: "hydrogen emission lines series excitation spectrum frequency", etc?

I'm not sure how a random google search is going to help.

Anyway, this question has already been solved here.
