REFRACTION AND REFLECTION SOUND AT THE INTERFACE BETWEEN WATER AND BUBBLE LIQUID
Abstract
The paper presents the results of a theoretical calculation of the phase velocity and attenuation coefficient for bubble liquid, reflection and refraction coefficients at normal and oblique incidence of the acoustic wave on the interface “water bubble water”, as well as the dependence of the angle of refraction on the frequency of perturbations and the angle of incidence. The analytical expressions and numerical calculations analysis revealed that in the case where the wave is incident from the bubble liquid on the interface, there is a critical angle of incidence to the low frequency domain, and at greater angles total internal reflection occurs. The paper shows that total internal reflection does not occur when the wave is incident from the water side on the interface.
