{{#category_index:S|slowness surface}} A constant-velocity surface calibrated in reciprocals of the phase velocity. The components of slowness parallel to an interface are identical for incident, reflected, and refracted waves (Snell’s law). In anisotropic media, SH and SV slowness surfaces may separate, have dimples, and touch or cross each other.
