Test 1

Test - Wednesday 09/28/2011 - Chapters 1-4

Test topics (Emphasis on Chapter 2 to reflect time spent):

  • Twin paradox - incorporating length, time, frequency relativistic effects (calculations)
  • Relativistic dynamics - energies/momentums of particles (calculations)
  • Photoelectric effect / Compton effect (calculations)
  • DeBroglie Wavelength / Heisenburg Uncertainty Principle (mostly conceptual)

Also: I would guess there would be somewhere between 4 and 6 problems on the exam - equal valued. You can bring in an equation card (3inch x 5inch) with anything you want *HANDWRITTEN* on it, and a calculator (you should not have equations "plugged in" to the calculator), and writing implements. You will write your answers on the test paper itself, no blue books needed.
