Spectral
Lines
-
Spectral lines were discovered
in spectra of the Sun by Joseph von Fraunhofer in 1814
-
Materials like salt sparkle
certain colors when thrown into flames
-
In 1857 Robert Bunsen created
a special burner (bunsen Burner) to study these effects
-
Fraunhofer (absorption) and
emission lines are related!
-
Every chemical element
has its own unique set of spectral lines
