WebSlowness (s) is a quantity introduced in Seismology which is the reciprocal of velocity. Thus travel time of a wave is the distance that the wave travels times the slowness of the medium ( in seismology, it refers to different layers of Earth exhibiting different densities ) Thus, Slowness = 1/Velocity. If we divide the path followed by the ray ... WebApr 26, 2024 · This equation tells us how the raypath vector changes along the curved raypath. The equation for the unit tangent vector is. The slowness is a scalar function that depends on coordinates x and y. However, we can hold y constant and consider the curve that gives the variation of slowness with x alone.
