In 1885, when Johann Balmer observed a spectral series in the visible spectrum of hydrogen, he made the following observations: The longest wavelength is 656.3 nm. The second longest wavelength is 486.1 nm. And the third is 434.1 nm. Also, as the wavelength decreases the lines appear closer together and weak in intensity.
