SpectrumSlide4
A hot object or a hot, dense gas produces a
continuous spectrum
-- a complete rainbow of colors without any specific spectral lines. Slide5
A hot, low density gas produces an
emission line spectrum
- a series of bright spectral lines against a dark background.Slide6
A cooler, low density gas in front of a hot dense gas produces an
absorption line spectrum
- a series of dark spectral lines among the colors of the rainbow.Slide7Slide8
Spectral Lines
By observing the location of the emission and or the
absorption lines, one can identify the element!!!!
