  • Discuss the experimental basis for the photon concept, and apply the concept to analysis of phenomena such as the photoelectric effect in metals and Compton scattering.
  • Cite and discuss examples of phenomena that illustrate the dual nature of light.
  • Determine and interpret solutions to the one-dimensional Schrodinger equation.
  • Compare models of atomic structure and apply wave mechanics to explain atomic and molecular properties (e.g. light spectra).
  • Apply the idea that the measurable effects of a gravitational field are equivalent to the observer being in an accelerated reference frame.
  • Apply ideas from wave mechanics to explain the measurable properties (e.g. conductivity) of crystalline solids.
  • Describe and classify subatomic particles in terms of mass, charge.
  • Describe the four fundamental interactions ("forces") and classify subatomic particles in terms of which interaction(s) affect their behavior.
  • Contrast and compare models of the evolution of the universe based on ideas from particle physics, general relativity and classical physics.
  • Discuss the experimental evidence for the rejection of the ether hypothesis and the conclusion that the speed of light is the same in all inertial frames.
  • Transform length, time and velocity measurements from one inertial frame to another in relative motion to the first.
  • Apply relativistic ideas regarding energy transformations to the behavior of real world objects.
  • Apply the energy and charge conservation laws towards the analysis of nuclear structure and reactions.
