Geophysics wave problem?
It is a common occurrence that seismic waves are generated on the sea surface and the waves rising from the seafloor (and layers below that) are monitored by a number of sensors (or geophones) on the sea surface. Suppose we have a sandstone seabed. Given that the speed of a P-wave in water is 1500 m/s and in sandstone is 3300 m/s calculate the critical angle for the seabed-sandstone interface.

sin^-1(1500/3300) = ?

Seismic waves both P and S waves refract depending the litholayers they penetrate.. you need to know the depth and density to understands the velocity and direction.
