Abstract
We have observed light scattering from the density variations in the first- and second-sound modes generated simultaneously by a thermal transducer in superfluid . Measurements of the temperature dependence of the density variations in both sound waves agree with the theoretical treatment by Lifshitz of the density-temperature coupling.
