Given for sandstone
density 1 = 2 Mg/m3
velocityV1 = 2.6 km/s
For shale
density 2 = 2.3 Mg/m3
velocity V2 = 2.8 km/s
Reflection coefficient (R) is the ratio between amplitude of the reflected wave and amplitude of the incident wave.
R = (2 V2 -1V1 ) / (2 V2 + 1V1 )
R = (2.3 Mg/m3* 2.8 km/s - 2 Mg/m3*2.6 km/s) / (2.3 Mg/m3* 2.8 km/s + 2 Mg/m3*2.6 km/s)
R = 0.1065
The amplitude diminishes as 0.1065 for reflections from the top of interfaces.
