Understanding Harmonics: Resonating Air Columns and Sound Velocity Measurement

Explore the fascinating world of harmonics on the guitar, focusing on open and closed-end resonating air columns. Learn how these concepts relate to the speed of sound, which can be measured with precision using tools like Audacity. This guide delves into wave velocity in various mediums, including aluminum, and discusses the fundamental frequency and length relationships in tubes. With practical applications in music and science, discover how sound behaves in different environments and learn to calculate sound velocity effectively.
