Z_{P} = ρ V_{P}

. In layer order limestone, sandstone, salt,

(Z_{P 1}, Z_{P 2}, Z_{P 3}) = (5.50, 4.00, 4.00) \times 1 0^{6} kg m^{- 2} s^{- 1} .

The salt's larger P-wave seismic velocity is exactly offset by its smaller printed density, so the second interface has no P-wave seismic impedance contrast in this stipulated model.
