Interference of 2-D Waves and Beats

Title: Interference of 2-D Waves and Beats

Category: 2D Wave Interference

Summary: I looked at the interference of 2D waves as well as the topic of beats since they are 2 sources interfering with one another. I chose to present my LO on a Prezzi because I think it would explain this topic best, and I decided to use one big question (2 speakers as sources) to explain the interference of 2D waves, how waves could interfere constructively or destructively. For beats, I showed the equations, explained them, and gave a simple example of how to calculate beat frequency.
