✦ Synopsis

Recent experiments by Olsen on the optical observation of second-sound resonance on the surface of liquid helium II are shown to be consistent with theoretical results derived fi'om Landau's two-fluid model. The theoretical developmem makes use of an approach originally taken by Usui and London. An alternative approach based on the Landau-Bernoulli equation is also discussed. The experiments of Olsen may ultimately provide a conclusive test of the theoretical approaches.
