Learning Outcomes
On successful completion of this module, students should be able to:

  • Express relativistic effects concerning the motion of a body, as observed in different inertial reference frames
  • Describe wave motion and relate it to basic phenomena in light and sound
  • Understand sources of errors in measurements and calculate their propagation.
  • Prepare a brief report, including error analysis, on a simple physical experiment
