Sound waves cause cork powder in a glass tube to move. If the sound wave's frequency matches a natural frequency of the tube's volume, a standing wave forms. The cork powder then creates a pattern showing pressure nodes and the standing wave's motion. Using the tube's volume length and the number of pressure nodes, one can calculate the speed of sound for each natural frequency.
