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
The light that leaves the cloud (right) shows absorption lines in the spectrum at ...
seen as dark lines, or lines of reduced intensity, on a continuous spectrum.
Aug 20, 2007 ... When light is passed through a prism or a diffraction grating to ... and absorption
lines (dark lines in an otherwise continuous spectrum) as ...
Today, we'll look at the processes by which emission and absorption lines are
created. .... spectrum of the Sun shows many, many, MANY dark absorption lines:
... the photosphere -- absorb some of the continuous light coming from the hot, ...
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
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
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, ...
They made a prism-based device that separated the visible light emitted ... of the
