Question
A refraction seismic survey is conducted in a region with a planar, dipping layer beneath a flat overburden layer. The surface is flat. The velocity of each layer is constant, and v1< v2<v3. Do you expect the reciprocal times from the dipping interface to match?
a. No, because the forward and reverse shots travel along different ray paths
b. Only if there is no noise in the data
c. Yes, because the forward and reverse shots travel along the same ray path
d. No, because the velocity in the up-dip direction is greater than in the down-dip direction
