Emission+and+Absorption+Lines

Emission and absorption lines can be easily found on a spectgraph. They can be identified as the large spikes and dips on a graph. To identify emission lines all you simply have to do is use your common sense to see that certain lines in the spectroscopy are much larger than the rest of the graph. The same goes for absorption lines as well, except they are large dips in the spectroscopy. One exception for absorption lines however is galactic and telluric bands. These are created from dust in space or the moisture in our atmosphere and are always on the same place on a graph.
