2D Wave Interference
Category: 2D Wave Interference
Summary: I found that I didn’t get enough clarification from the pre-reading on wave interference so my Learning object explains the basics of this phenomena in a powerpoint format. I distinguish between destructive and constructive wave interference. I also introduce the path difference equation which is key in solving future problems regarding wave interference.

Title: Propagation of Waves in Relation to Energy and Huygens’ Principle
Category: Wave Propagation and Huygens Principle
Summary: This learning object adresses the Huygens’ Principle and the concept of conservation in relation to wave energy. I chose the multiple choice question format.
Beats and Beat Frequency
Title: Beats and Beat Frequency
Category: Beats
Summary: This powerpoint presentation describes what beats are, as well as what beat frequency is. It describes how tuning is associated with beat frequency. There are two video links to help better understand what beats are, as well as what the resultant amplitude of two interfering sound waves are.
