Question

2)Identify the initial and final states if an electron in hydrogen emits a photon with a wavelength of 1282.0 nm. Enter the initial state first

Answer 1

The lower state quantum number is not 1 or 2; those would be Lyman or Balmer series lines in the UV or visible. The lione mentioned in in the near infrared. Try nf=3 and nf=4 and various combinations of the Rydberg formula.

Hint: This is a Paschen series line.
