So the Balmers constant is cool and easy to use compared to the Rydberg constant and I was looking for something simpler and came up with this. If you change the Balmers constant to B=91.126705 by dividing it by 2² (because 364.50682 is the Balmers series) and use the formula. Wavelength = BN²(n²/(n²-N²)) N being the series N=1 lyman N=2 Balmers etc. Now I can use the Balmers to calculate all the wavelengths of hydrogen with ease and answers in nm. Any thoughts on this I tested it out and it looks to work great maybe someone else could give it a go and make sure it works thanks.
