On Sound Reflection in Superfluid
arXiv:0707.0083 · doi:10.1007/s10909-007-9534-3
Abstract
We consider reflection of the first and the second sound waves by a rigid flat wall in superfluid. Nontrivial dependence of the reflection coefficients on the angle of incidence is obtained. Sound conversion is predicted at slanted incidence.
