Mercury spectral lines
WebThe most prominent mercury lines are present at 546.074 nm which is green in color, 435.835 nm that is blue in color, and at 579.065 nm and 576.959 nm that is yellow orange in color. There are also two other blue spectral lines present at 407.781 nm and 404.656 nm and also a weak line present at 491.604 nm. Web7 mei 2015 · The graphical representation should include all visible lines shown in the color specrum. The continuum should rise gradually from 4000 angstroms, and remain fairly constant through blue, and decrease slightly in green portion of the spectrum. It should increase again, reach a maximum near yellow, and then decline again in the red.

WebSpecifically, much of the intensity resides in the sharp mercury lines, and the output is poor in the critically important actinic UV region from 290 to 340 nm. In addition, the intensity … A mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce light. The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger soda lime or borosilicate glass bulb. The outer bulb may be clear or coated with a phosphor; in either case, the outer bulb provides thermal insulation, protection from the ultraviolet radiation t…
