Module 2: Atoms and Light: The Interaction and Nature of Light and MatterSupplements and Credits
Supplement the videos with "OpenStax Astronomy"
01: The Nature of Light, Part 1Wherein we discuss the nature of light and a summary of its wavelike properties.
02: The Nature of Light, Part 2Wherein we discuss what exactly a photon is, and how it makes up all the colors of the electromagnetic spectrum.
03: Stellar Brightness and MagnitudesIn this one, we define the terms, brightness and luminosity. We also define the magnitude system, both apparent and absolute. We don't shy away from equations anymore! We also derive how Pogson saddled all the future of astronomy with a Log-base-10 humbug.
04: Color and TemperatureHere we chat about how we exactly define color in astronomy using broadband filters. We also detail how color relates to temperature, what temperature actually is, and how blackbody radiation manifests in everyday life and in stars.
05: Kirchhoff's Laws of SpectroscopyHere we discuss the empirical methods of learning how light interacts with matter.
06: Atoms, Elements and IsotopesHere we discuss the current state of knowledge about atoms, elements and isotopes. We chat about the periodic table, atomic numbers, what an atom is, how big they are, how they interact. Also, about radioactivity and what makes them unique.
07: The History of the AtomHere we talk about the origin of the atom from Democritus, to Plato and Aristotle to Dalton, to Thomson to Rutherford. All of the ways it's evolved, both philosophically and as a result of experiment.
08: The Bohr Model of the AtomThe Bohr Model of the atom is the standard way that introductory astronomy textbooks seek to demonstrate the link between atomic spectra and Kirchhoff's Laws of spectroscopy. It's important to motivate it with the essentials of quantum mechanics. Here, we add in Einstein's and deBroglie's and Schroedinger's contributions, but we lean back towards the "Astro 101" understanding of the atom.
