Emission Series:Another Look (Hydrogen) What do we use Emission Spectra for?
Emission Spectra is unique to individual elements
Spectra can be collected and matched to known emission spectra to determine the
Hydrogen Emission Spectra Fe Emission Spectra
Flame test Emission/Absorption Spectra
Lines in visible region shown above (Hydrogen shown)
Also some occur in other spectral regions and aren’t seen without detectors Emission Spectra:Applications inAstronomy •Spectra is collected •Compared to known ions •Temperatures known
