• Wave particle duality
• Energy of a photon E ? f
• Light intensity determines number of photons per
  second frequency determines energy per photon
  all photons travel at the same speed
• Photoelectric effect
• Blackbody radiation and the ultraviolet
  catastrophe
• Compton effect
• de Broglie wavelength ?h/ph/mv
• Energy level diagrams, line-emission spectra
• and spectroscopy
• Alpha, beta, and gamma decay
