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 ...
Spectroscopy pertains to the dispersion of an object's light into its component
colors ... With discrete spectra, one sees only bright or dark lines at very distinct
and ... are called emission spectra, those with dark lines are termed absorption
spectra. ... Continuous spectra arise from dense gases or solid objects which

Within this spectra, astronomers can study emission and absorption lines ... The
light is spread out into a continuous band with every wavelength having ... If you
look more closely at the Sun's spectrum, you will notice the presence of dark lines
When this light is decomposed using a prism it is found to be made up of a series
of ``lines'', that is, the output from the prism is not a smooth spectrum of colors, ...
A low density, cool gas in front of a hotter source of a continuous spectrum
creates a DARK LINE or ABSORPTION LINE spectrum. You can also summarize
Simply stated, light is nature's way of transferring energy through space. ... no
