Resonance occurs when an object is made to vibrate at its natural frequency, and the vibrations reinforce themselves, becoming larger. In the case of sound, the object can be a column (or other vessel) of air, and the larger vibrations are observed as a louder sound. In this lab, students will use a tuning fork to find the resonance point of a column of air. Then they will use a simple formula to find the speed of sound.
