  • 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

  • i1

    i2

  • Reflected and transmitted P and SV waves

  • Reflected and transmitted SH waves
