The simplest mechanism of the observed S wave excitation is the P -to- SV conversion on the sea bottom during multiple reflections within the ocean ( 7 ).
WebbIf the slowness vector is known at a given point x in the model, the ray vector r = [r 1, Tr 2, r 3] generally not in parallel with the slowness vector can be calculated as (Červenỳ, 2001)
Slowness (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 into N segments numbered i = 1, 2 ..
