    • 3.1: Blackbody Radiation
      Electromagnetic radiation emitted by a hot object distributes the emitted energy in a specific manner across the spectrum of possible wavelengths. Explaining this distribution was problematic when this phenomenon was first measured in the 19th Century, and even the fellow (Max Planck) who solved the problem mathematically didn't believe his own solution.
    • 3.2: The Photoelectric Effect
      The paper on Special Relativity published in 1905 was not the only one that Albert Einstein published in that year. In this section, we will explore his 1905 explanation for what happens when light interactions with electrons on the surface of a metal.
    • 3.3: Compton Scattering
      The photoelectric effect is not the only phenomenon that provided puzzling experimental results related to light's interaction with matter. Scattering light off clouds of particles explores the momentum transfer aspect of these interactions that cannot be seen when the particles are on a metal.
    • 3.4: Matter Has Wave Properties, Too!
      We have seen many cases of light behaving like a tiny particle under the right conditions.  What about the reverse?  Could a tiny particle like an electron behave like a wave under the right conditions?
