PhET Simulations for Learning the Physics of Music


University of Colorado Boulder Prof. Ed Kinney uses PhET’s Wave on a String to teach principles of sound in his popular physics course, Sound and Waves. In the course, students learn what happens to the waves as they move through the air from a speaker or musical instrument into the ear and vibrate the parts of the inner ear. Kinney says that PhET sims such as Wave on a String show changes and movement of sound through time better than a still image: “There’s not a still picture in a book that you can get across what is happening in real time when sound waves come into your ear.  Still pictures don’t convey the understanding.”
