Rydberg constant wavelength

In 1880, Rydberg worked on a formula describing the relation between the wavelengths in spectral lines of alkali metals. He noticed that lines came in series and he found that he could simplify his calculations using the wavenumber (the number of waves occupying the unit length, equal to 1/λ, the inverse of the wavelength) as his unit of measurement. He plotted the wavenumbers (n) of successive lines in each series against consecutive integers which represented the order of the l… WebThe spectrum of hydrogen and the Rydberg constant In this experiment you will use a diffraction-grating spectrometer to measure the wavelengths of the emission lines of …
