Demonstrations with the singing rods
Held at the middle and stroked along its length, each rod vibrates longitudinally and sings; comparing rods of different length shows how pitch depends on length, and comparing thick with thin or solid with hollow lets students test whether the cross-section matters.
- Demonstrating longitudinal vibrations and resonance in a rod
- Showing how pitch depends on rod length
- Testing whether thickness or a hollow section changes the note
- Estimating the speed of sound in the rod from its length and frequency
