Mercury absorption spectrum
WebWhen the light from a distant gas cloud (nebula) is examined, it shows a line absorption spectrum. The line emission spectra of hydrogen (H), mercury (Hg) and neon (Ne) are shown. WebThe prominent mercury lines are at 435.835 nm (blue), 546.074 nm (green), and a pair at 576.959 nm and 579.065 nm (yellow-orange). There are two other blue lines at 404.656 nm and 407.781 nm and a …
