the resonance of a bottle

Presets
Blow across a bottle and it sings at its Helmholtz frequency. The plug of air in the neck acts as a mass and the air in the cavity as a spring, giving f = (c/2π)√(A/VL). Bigger cavities and longer necks lower the pitch — the principle behind bass ports, mufflers, and ocarinas.

Resonant frequency167 Hz

Cavity500 cm³
Governing equation
Reading this result: This cavity sings near 167 Hz — a 2.05 m wavelength. Enlarge the cavity or lengthen the neck and the pitch drops, because both add to the mass-on-a-spring that sets the tone.
