Common Phenomena in Periodic Systems (10 minutes)

  • This course focuses on studying the phenomena that occur in periodic systems. In particular, we will discuss three observable events in depth.
    1. Sound waves in a crystal.
      • Specifically, this event results from the mechanical displacement of atoms in the crystal from equilibrium.
      • Calculation one might do: Finding the speed of sound in a solid.
