Emission spectrum helium
http://hyperphysics.phy-astr.gsu.edu/hbase/quantum/atspect2.html WebThe Helium Spectrum. There are three spectral lines for helium, {438.793 nm, 443.755 nm, 447.148 nm} for which the best explanation is a transition of an electron from quantum number 5 to quantum number 2 while the other electron remains at quantum number 1. The wave length is given by the equation ΔE = hc/λ = R(1/n 3 ² − 1/n 1 ²) hence
