3B Scientific™ Helmholtz Resonator
Hollow glass bulb with a narrow tube leading out for demonstrating acoustic resonance.
Supplier: 3B Scientific™ U8430320
Description
Oscillation is generated by blowing into the opening or banging on the outside of the bulb. The elasticity and inertial mass of the air in the bulb cause the bulb to act as an acoustic resonator with a highly distinct resonant frequency. The frequency is dependent on the dimensions of the bulb and the tube.
- Opening on the glass bulb: 14mm dia.
- Length of tube: 15mm
- Resonant frequency: 1440Hz.
