Seismic reflection is a method of exploration geophysics that provides information about the sub-surface structure of the seafloor. The general principle involves sending artificially generated acoustic waves down the water … P-waves, also known as primary waves or pressure waves, travel at the greatest velocity through the Earth. When they travel through air, they take the form of sound waves – they travel at the speed of sound (330 ms-1) through air but may travel at 5000 ms-1 in granite. Because of their speed, they are the first … Ver mais S-waves, also known as secondary waves, shear waves or shaking waves, are transverse waves that travel slower than P-waves.
