sci.bohr-hydrogen-energy Calculator
Calculates hydrogen energy levels E_n = −13.6/n² eV and electron orbital radius r_n = n²a₀ from principal quantum number n, and the wavelength of photon transitions. Ground state energy = −13.6 eV; Lyman series (to n=1) is UV; Balmer series (to n=2) is visible — the Hα line at 656 nm gives stars their characteristic reddish colour.
