Imagine a simple crustal structure, with a granitic crust (Vp=6000 m/s, density=2.67 gm/cm3, Poisson's ration 0.25) overlying mantle (Vp=8000 m/s, density=3.3 gm/cm3, Poisson's ratio 0.30).
Using the Crewes Zoeppritz Explorer, determine the distance at which the critical reflection appears on a wide-angle reflection section, if the crust is 30 km thick.
