WebThese colors can be used to produce atomic emmision spectra of the elements electrically excited. Using known values of emmision spectra, one can perform a similar discharge test on un unknown gas, gather an emmision spectrum from it, and determine which elements are in the unknown gas. WebExplanation: Above is an image of the relatively quiet Sun made on May 18 in light emitted by ionized Helium atoms in the Solar chromosphere . Helium was first discovered in the Sun in 1868, its name fittingly derived from from the Greek word Helios, meaning Sun. Credit for the discovery goes to astronomer Joseph Lockyer.

Web1. If we assume (or can show) that a star lies on the main sequence, we can use its color index to estimate its absolute magnitude.
