GEOLOGY

Detailed explanation-1: -A P wave is commonly referred to as a pressure wave or a primary wave in the elastic body, also known as seismic waves. The study of such waves is called seismology. These waves travel through solid, liquid, and gas.

Detailed explanation-2: -Compressional waves are also called P-Waves, (P stands for “primary") because they are always the first to arrive.

Detailed explanation-3: -Compressional waves are also known as a longitudinal waves because of the way in which they travel through a medium.

Detailed explanation-4: -P Waves. P waves are compressional waves that do not produce much damage. They can move through any type of material and travel at almost twice the speed of S waves. High frequency P waves do not weaken, or “attenuate, ” as rapidly as S waves so they retain higher frequencies when they arrive at seismic stations.

Detailed explanation-5: -In P or compressional waves, the vibration of the rock is in the direction of propagation. P waves travel fastest and are the first to arrive from the earthquake. In S or shear waves, rock oscillates perpendicular to the direction of wave propagation.
