Helium emission color
WebThe color of the light produced depends on the emission spectra of the atoms making up the gas, as well as the pressure of the gas, current density, and other variables. Gas discharge lamps can produce a wide … Web28 mei 2014 · The emission spectra of different elements are unique, so the spectra given off by hydrogen will be different than that of helium. The different colors of light produced by emission spectra of different elements allows them to be identified. One use of this technique is to identify the elements present in distant stars.
