According to the equation for the balmer line spectrum of hydrogen, a value of n=3 gives a red spectral line at 656.3 nm, a value of n=4 gives a green light at 486.1 nm, and a value of n=5 gives a blue line at 434.0 nm. according to these wavelenghth differences between lines in the balmer series become smaller as n becomes larger, at what wavelenghth in nanometers do the lines converge.
