Problem

Bubbles of radius R0=2.0 mmR_0 = 2.0\,\mathrm{mm} are heard gurgling in a brook (water at ρ=1000 kg m−3\rho = 1000\,\mathrm{kg\,m^{-3}}, ambient pressure p0=101.3 kPap_0 = 101.3\,\mathrm{kPa}, gas polytropic index κ=1.4\kappa = 1.4). Surface tension may be neglected at this size. Find the Minnaert frequency of these bubbles.
