Neon emission spectrum colors
http://chemed.chem.purdue.edu/demos/main_pages/6.5.html WebThe familiar red color of “neon” signs used in advertising is due to the emission spectrum of neon shown in part (b) in Figure 6.13 "The Emission Spectra of Elements Compared with Hydrogen". Similarly, the blue and yellow colors of certain street lights are caused, respectively, by mercury and sodium discharges.

WebSpectral lamps are basically always gas discharge lamps with a low gas pressure, so that pressure broadening (spectral broadening based on frequent collisions during the emission of atoms or ions) is largely avoided. With that, one typically obtains light emission on several spectral lines.. In principle, one can call such lamps arc lamps in the sense that … WebBohr's model of hydrogen is based on the nonclassical assumption that electrons travel in specific shells, or orbits, around the nucleus. Bohr's model calculated the following energies for an electron in the shell, n. n …
