Modern Unit test Review

Here are the overall subjects we have covered in this unit.  The test will be comprised of 30 multiple choice questions, 3-4 written  questions and 2 calculations.  The test is currently scheduled for October 6th (2nd) and 7th (6th).


Modern Physics

Fundamental Forces –Gravity, EM, Strong & Weak Nuclear Force
Modern vs. Classical Physics (Relativity vs. Simultaneity)
Unified Theory (Gen Rel + Quantum
Principles/Laws
          Cosmological Principle
          Heisenberg Uncertainty
          Symmetry Principle
          Pauli Exclusion Principle.

Cosmology

 -Theories (Steady State, Big Bang, Inflation, Superstring,etc,)
  -Advantages/Disadvantages with theories
 -General Relativity (Space-Time)
 -Role Dark Matter/Dark Energy
 -Structure of the Universe (Filaments, Voids, Clusters, etc.)

Particle Physics

-Models of the Atom (Plum Pudding, Rutherford, Bohr, Electron Cloud)
-Properties of Sub-atomic particles (Nucleons and Electrons)
-Properties or Hadrons/Leptons/Gauge Bosons
-Mediating Particles/Feynman Diagrams
-Particle Interactions (Legal or not….)


Nuclear Physics
-Mass Defect/Binding Energy (Calculate, explain)
"Natural" Radiation
    -Nuclear Decay Sequences and types
    -Applications of Decay/Decay Sequences (Determine Transmutations; radio metric dating; nuclear medicine)

Nuclear Processes
   -Fission (Process)
   -Fusion (Process)
  -Applications
  - Health Effects
  - Accidents and long term consequences
