Lecture 5: Beat Phenomena

« Previous | Next »

Lecture Topics

  • Coupled oscillators
  • Beat phenomena
  • Normal axis

Lecture Video: Beat Phenomena

Prof. Wyslouch shows the solution of two coupled pendula. A very interesting result from the calculation is that beat phenomena could be identified in the motion of the pendula, similar to what one could feel with sound waves.
