So I happen to be in the chorus room for parent teacher conferences and figured this would be a great opportunity to do a demo with sound that I have been meaning to get to. The video has to do with the superposition of waves using a guitar. This image represents a whole bunch of possible standing waves that can take place on a string of length L.
When you play a note on a guitar you are making these waves, but they all happen at the same time. Imagine adding all of those waves together, the resulting interference is referred to as superposition. Check out this video I made demonstrating the idea of superposition: multiple waves existing at the same place at the same time.
