Hi all. This is my first time on these boards, and I'm hoping you'll be able to help me out. I'm studying for a quiz I have in a few days, and I've realized that I missed one on my homework that I didn't notice, and I don't know how to answer it correctly.
Question: One of the emission lines of the hydrogen atom has a wavelength of 94.9 nm.
a). In what region of the electromagnetic spectrum is this emission found?
microwave, gamma ray, infrared, radio frequency, ultraviolet, x-ray, visible
b). Determine the initial and final values of n associated with this emission.
I think that the answer to a is ultraviolet, based on

Thank you all in advance.
