Transitions down to $n=2$ form the Balmer series: the first lines $(6563\mathring{A}$ to $\sim 4000\mathring{A})$ lie in the visible, while lines from still higher $n$ approach the series limit $3646\mathring{A}$, in the ultraviolet. So the set is a mixture of visible and ultraviolet. \end{document}
