Question

List all the spectral lines of hydrogen that lie in the visible range (taken to run from 400 to 700 nm in wavelength).

Express your answer numerically. If there is more than one answer, enter your answers separated by commas in order of increasing wavelength.

Answer 1

λ= 410,434,486,656 nm
6 - 2 91.18nm/(1/2^2-1/6^2) = 410 (410.31)
5 - 2 91.18nm/(1/2^2-1/5^2) = 434 (434.19)
4 - 2 91.18nm/(1/2^2-1/4^2) = 486 (486.293)
3 - 2 91.18nm/(1/2^2-1/3^2) = 656 (656.496)
