On Sound Reflection in Superfluid

On Sound Reflection in Superfluid

We consider reflection of first and second sound waves by a rigid flat wall in superfluid. A nontrivial dependence of the reflection coefficients on the angle of incidence is obtained. Sound conversion is predicted at slanted incidence.
