In particular, the interstellar cloud contains the single absorption line at around 585 nm just like …

Nettet10. aug. 2015 · Hydrogen. Helium. Carbon. We know that the continuum of the electromagnetic spectrum extends from low-energy radio waves, to microwaves, to infrared, to optical light, to ultraviolet, to X-rays and gamma rays. In the same way, hydrogen's unique spectrum extends over a range, as do the spectra of the other … NettetThe 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/n3² − 1/n1²) hence
