WebP-wave refraction. P-wave refraction evaluates the compression wave generated by the seismic source located at a known distance from the array. The wave is generated by vertically striking a striker plate with a sledgehammer, shooting a seismic shotgun into the ground, or detonating an explosive charge in the ground.Since the compression wave is … Webwaves,mostlyP-waves,intheirtransmission,reﬂection,diffraction,refraction,andturning processes. The processing of other seismic data and many non-seismic data often follows similar principles. The purpose of acquiring and processing seismic data is to learn something about the Earth’s interior.
