    This educational video produced by Encyclopedia Britannica explains the science of sound. The physics of sound effects are made easy to understand. There are three basic sources of sound: vibrating columns of air, vibrating surfaces, and vibrating strings. Many examples are given of how sound is produced, such as how each musical instrument, even when playing the same note, creates different tones because of the way the sound is made. This creates the unique sound an orchestra makes when playing a symphony. Answering the question "How does sound travel?" is not easy to do in a science video made to be understood by all, but this film uses tuning forks, oscilloscopes, and basic animation to make science sound waves easy to understand.
