Detailed explanation-1: -P waves are also known as compressional waves, because they push and pull. Particles subjected to a P wave move in the same direction that the wave is moves in; it is the direction that the energy is traveling in, sometimes called the “direction of wave propagation.”
Detailed explanation-2: -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-3: -Answer and Explanation: P waves move faster than S waves, and they can travel through gases, solids and liquids. As they move, P waves push and pull on whatever material they travel through. This pushing and pulling action has earned P waves the nickname push-pull waves.
Detailed explanation-4: -The P wave can be described as a push-pull wave, because it moves by contracting and expanding material along a horizontal path. A P-wave travels through a material as a compressional force. The second major type of seismic wave is called an S-wave. S-waves are shear waves.
Detailed explanation-5: -P-Wave : The fastest wave, and therefore the first to arrive at a given location, is called the P-wave (primary or push-pull). The P-wave alternately compresses and expands material in the same direction it is traveling.
