(A) Determine the wavelength of light absorbed in an electron transition from n = 2 to n = 4 in a hydrogen atom.

(B) Refer to Figure 8-13 and determine which transition produces the longest wavelength line in the Lyman series of the hydrogen spectrum. What is the wavelength of this line in nanometers and in angstroms?
