Spectroscopy videos (i.e., Spectroscopy videos):
1. Emission spectrum of hydrogen | 0:57: Shows the formation of emission line spectra. The diagram of an atom is abstract, NOT realistic. Real atomic states (i.e., atomic energy level) are NOT circular circular orbits, but cloud-like structures. In fact, atoms look like fuzzy little balls because they are fuzzy little balls. Good and short enough for classroom.
2. Spectrum of the Stars | 0:54: Shows the formation of absorption line spectra and emission line spectra. Good and short enough for classroom.
