My task is
Let's consider a model made up of two horizontal layers: the upper layer has a velocity
Vp1=3.0 km/s and the lower layer (or half space) has a velocity Vp2= 5.0 km/s. Aseismic experiment is conducted at the surface and showsthat the P wave refracted in the lower layer has a critical distance of 7.5 km and a critical time of 4.17 s. Based on this information, what is the thickness of the upper layer?
1. can i solve this by useing ti= (2z(v2^2 -v1^2)^1/2) / (v1*v2) and then
z= (ti*v1*v2) / 2(v2^2-v1^2)^1/2?
2. Is critical distance the thickness of layer 2?
greatful for any help
