-
Δs = Δx sin θ
Δs = v ΔtΔt / Δx = sin θ / v = p
p = ray parameter
Plane wavefront and ray parameter
-
Δt / Δx = p
p = ray parameter
Ray parameter and travel time curve
-
V1 < V2
Wavefronts at evenly spaced times. Different separation due to different velocities. -> Ray angle changes.
i1
i2
Wavefronts across interface

Reflected and transmitted P and SV waves
