Beats

Mr. Anderson explains the concept of beats in physics, which occur when two waves with close frequencies interact, causing changes in amplitude. He demonstrates how beats can be used practically, such as in tuning musical instruments, and explains the interference that causes these amplitude changes. The video also covers how to calculate the frequency of beats using the difference between two frequencies. A practical demonstration using Audacity software illustrates these concepts, showing how slightly different frequencies result in audible beats.

How do you calculate the frequency of beats?

What happens to the beats when two waves have the same frequency?
