We’re being asked to calculate for the wavelength of light absorbed by a ground-state hydrogen atom to cause an electron to transition to n = 3.


We’re going to use the Balmer Equation which relates wavelengths to a photon’s electronic transitions.

1λ=RZ21n2final-1n2initial

λ = wavelength, m
R = Rydberg constant = 1.097x107 m-1 
Z = atomic number of the element
ninitial = initial energy level
nfinal = final energy level


Calculate the wavelength of light absorbed (λ):
