Spectroscopy - 5a - Intro to Astronomy Sessions

A brief overview of how spectral lines are formed by different elements, under what conditions, and how we can use them as chemical fingerprints. Full Series Playlist:    • Intro to Astronomy Sessions   The Sloan Digital Sky Survey, where you can access a lot of raw spectral data for stars, galaxies, and more: https://skyserver.sdss.org Please note that this was designed as an introductory survey of astronomy course, mostly for non-science majors, and does simplify many of the topics accordingly. I encourage people who are just getting into astronomy to use this as a jumping off point for more in depth studies. I've tried to edit out specific references to my course (regarding assignments, tests, etc.) but I might have missed some. Finally, scientific fields are constantly advancing, with new data and studies resulting in our ideas being continually improved. This means some of the ideas presented here may soon be out of date, so I again encourage people to continue to investigate whichever topics are of particular interest to you.
