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

Wave unit Review
