Angles Of Reflection And Refraction
Consider a P-wave which is incident at an angle $\theta_1$ measured with respect to the normal of the interface, as seen in the figure below where the approaching wave is represented as a ray. The angles of the reflected and refracted rays are as follows:
If the wave travels from a low velocity medium to a high velocity medium the wave gets refracted away from the normal. Conversely, it gets refracted toward the normal if the wave goes from a high velocity to a low velocity medium.

The critical refraction angle, called $\theta_c$, is a key concept in refraction seismology.
This is the angle of incidence for which the corresponding angle of
