What is the wavelength of the electromagnetic radiation emitted from a hydrogen atom when the electron undergoes the transition n = 5 to n = 3?(http://www.webassign.net/ebgam9/7-figure-05.gif) is a spectrum
m In what region of the spectrum does the line occur?
near ultraviolet
far ultraviolet
near infrared
far infrared
visible

Both near ultraviolet and far ultraviolet are wrong I put 2.27e-7 for the answer and was wrong and then I put 2.53e-7 in it was wrong as well.

Come on. Paschen series in infared, n5 6o n3 would be closest to visible, or near infared.

But your book may define 1281.81 nm as other classifications, so check.
