Detailed explanation-1: -The P wave, or primary wave, is the fastest of the three waves and the first detected by seismographs. They are able to move through both liquid and solid rock. P waves, like sound waves, are compressional waves, which means that they compress and expand matter as they move through it.

Detailed explanation-2: -P waves travel through solid and liquid, but S waves do not travel through liquid.

Detailed explanation-3: -P Waves. The first kind of body wave is the P wave or primary wave. It’s the fastest kind of seismic wave, and the first to arrive at a seismic station. P waves can move through solid rock and fluids, like water or the liquid layers of the Earth.

Detailed explanation-4: -P-Waves or the primary waves are also known as longitudinal or compressional waves. It can pass through solid, liquid and gas. P-waves travel at the fastest speed through solid materials. Though these also pass through liquid and gaseous materials their speed is slowed down.

Detailed explanation-5: -P waves can travel through liquid and solids and gases, while S waves only travel through solids. Scientists use this information to help them determine the structure of Earth. For example, if an earthquake occurs on one side of Earth, seismometers around the globe can measure the resulting S and P waves.
