A spectral line is a dark or bright line in an otherwise uniform and continuous
spectrum, resulting from emission or absorption of light in a narrow frequency ...
Sources of continuous, emission, and absorption spectra ... direction as the
absorbed photon, this gives rise to dark lines (absence of light) in the spectrum.
When photons from the light source make their way through this gas, some of

Spectroscopy pertains to the dispersion of an object's light into its component
colors (i.e. ... For a continuous spectrum, the light is composed of a wide,
continuous ... With discrete spectra, one sees only bright or dark lines at very
distinct and ... are called emission spectra, those with dark lines are termed
Today, we'll look at the processes by which emission and absorption lines are
