Compressional waves, or P-waves, are the most common type of seismic wave used for reflection prospecting. P-waves propagating through the Earth behave similarly to sound waves propagating in air. P-waves generate echoes (reflections) when they come in contact with an acoustical contrast in the air or under the ground.
