Fig. 4

a Schematic diagram showing the 3 main styles of bubble bursting and airwave excitation. Left : a hemispherical cap bubble sits at the surface and bursts, exciting a high-frequency (HF) wave. A “?” indicates that the modes are unknown. Middle : a bubble bursts while it is rising and excites Helmholtz resonance (mostly with HF wave component), and later vents an air flow. Right : a bubble bursts while it is rising and vents an air flow. b A regime diagram in the parameter space of suspension \(\phi\) and bubble volume V. A broken curve indicates the main regime boundary (see text for details)
