Rayleigh wave definition geology
WebJan 12, 2024 · Rayleigh waves, which travel only along Earth’s surface, have a rolling motion very similar to surface waves on the ocean. Rayleigh waves typically are larger and cause more damage than the faster-moving seismic P-waves and S-waves. S waves (in geology) Short for secondary waves, these are one of the types of seismic wave WebThis means the Rayleigh number is a type of Péclet number.For a volume of fluid of size in all three dimensions [clarification needed] and mass density difference , the force due to …
