PHYSICS 320: GENERAL PHYSICS II, FALL 2009

Tim Gfroerer, Davidson College

 

Topics on Review #3

 

 

  • Solving the 3D spherical Schroedinger equation: H atom quantum numbers

  • Spherical coordinate probability densities

  • Angular momentum, magnetic moment, and external B-fields

  • Spin-orbit coupling and adding angular momenta

  • Finite lattices and energy bands

  • Periodic lattices: the Kronig-Penney model

  • Insulators, semiconductors, and conductors

 

Some equations and numbers you should know:

  • QM probability, normalization, and expectation
  • Allowed quantum numbers, magnitude of angular momentum
  • Hydrogen atom energy levels (-13.6eV / n2)
  • Magnetic moment of a current loop and energy in B-field
  • The deBroglie free particle wavefunction
  • The Bloch wavefunction
  • Effective mass
  • Speed of Light
  • Electron Charge
  • Planck's Constant
  • Bohr radius (~ 0.5 Angstroms)

Some equations and numbers I'll provide if necessary:

  • 3D spherical Schroedinger equation
  • Hydrogen atom wavefunctions
  • Kronig-Penney transcendental equations
  • Electron Mass
  • Bohr magneton
  • Fine structure constant
  • Boltzmann constant
