: evolution of the shock velocity in time for SiO₂ and H₂O extracted from Figure 4: VISAR-1 (black) and VISAR-2 (yellow). : the reflectivity vs. time. This shows an increase after the shock enters the SiO₂ layer owing to the reverberating wave in SiO₂ (at about t ≈ 3-4 ns), and a second increase appears when the shock passes the SiO₂-H₂O interface at time t₁. Shock velocities are listed in Table 1 (SID-43058).
