We’re being asked to assign 1282 nm to transitions in the hydrogen atom.
We can see that the three wavelengths correspond to Paschen/Bohr series with nfinal = 3
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 initial energy level (ninitial):
An atomic emission spectrum of hydrogen shows the following three wavelengths: 1875 nm, 1282 nm, and 1093 nm. Assign these wavelengths to transitions in the hydrogen atom.
For nm = 1282 .
