We visit a university orchestra to help us understand wave interference and how resonance affects waves moving through different types of air columns and strings. We explore how to find various resonant frequencies using the wave velocity equation in combination with an equation that relates the wavelength of a wave to the length of a string, or a closed, or open-ended tube.
