Calculation Methodology
Rydberg Equation: 1 / λ = R_H * [ (1 / n1²) - (1 / n2²) ]. Where R_H is the Rydberg constant (1.097373 x 10^7 m^-1), n1 is lower principal quantum level, n2 is higher level. Photon Energy: ΔE = 13.606 * [ (1 / n1²) - (1 / n2²) ] eV.
Frequently Asked Questions
The Balmer series (n1 = 2); electron drops from n2 = 3, 4, 5, and 6 produce the four famous visible spectral lines (red 656 nm, cyan 486 nm, blue 434 nm, violet 410 nm).
