“Introduction to Astrophysics” S:1 E:8 Photons and Particles

S:1 E:8 Photons and Particles Investigate our prime source of information about the universe: electromagnetic waves, which consist of photons from gamma ray to radio wavelengths. Discover that a dense collection of photons is comparable to a gas obeying the ideal gas law. This law, together with the Stefan-Boltzmann law, Wien’s law, and Kepler’s third law, help you make sense of the cosmos as the course proceeds.
