GEOLOGY

Detailed explanation-1: -The Primary waves or Push waves are longitudinal / compression waves that vibrate parallel to the direction of wave movement. They have shortest wavelength, fastest speed 5-7 km/s and can travel through solid, liquid and gas.

Detailed explanation-2: -In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave. For example, sound waves are P waves at a high enough frequency to hear with your ear. An example of an S wave is wiggling or shaking a rope which is tied down at one or both ends.

Detailed explanation-3: -S Waves. The second type of body wave is the S wave or secondary wave, and are easy to remember because they’re the second wave to arrive after an earthquake. An S wave is about 1.7 times slower than a P wave. The biggest difference is that S waves can’t move through liquids.

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: -S-Waves. Secondary, or S waves, travel slower than P waves and are also called “shear” waves because they don’t change the volume of the material through which they propagate, they shear it.
