An equation for the wavelengths of the spectral lines of hydrogen, 1/λ = R [(1/ m 2) - (1/ n 2)], where λ is the wavelength, R is the Rydberg constant, and m and n are positive integers (with n larger than m) that give the principal quantum numbers of the states between which occur the transition giving rise to the line.
