Lyman-##\alpha## Wavelength: Hydrogen's Region in Spectrum

[tryingtolearn1]

TL;DR

Lyman wavelength

I am learning about the hydrogen atom and in my book it discusses the Lyman-$\alpha$ wavelength and I am wondering in what region in the spectrum is the Lyman-$\alpha$ for hydrogen?

Um... google? https://en.wikipedia.org/wiki/Lyman-alpha_line
I literally searched for the last few words in your question and picked the first result.
Or perhaps I misunderstood your question?

I think it's UV. The visible part of the spectrum ($\lambda$ between about 400 and 800 nm) is the Balmer series, i.e., transitions between $n>2$ and $n=2$ hydron energy states.

Concur. This pictures from right to left the visible Balmer series of Hydrogen:

and this pictures the Hydrogen spectra on a logarithmic scale with visible wavelengths labeled:

Probably a bit 'overkill' for the OP's question but should be of interest. 121.6 nm UV range.
