Detailed explanation-1: -There are two broad classes of seismic waves: body waves and surface waves. Body waves travel within the body of Earth. They include P, or primary, waves and S, or secondary, waves. P waves cause the ground to compress and expand, that is, to move back and forth, in the direction of travel.
Detailed explanation-2: -There are three basic types of seismic waves – P-waves, S-waves and surface waves.
Detailed explanation-3: -There are two types of seismic waves, primary waves and secondary waves. Primary waves, also known as P waves or pressure waves, are longitudinal compression waves similar to the motion of a slinky (SF Fig. 7.1 A). Secondary waves, or S waves, are slower than P waves.
Detailed explanation-4: -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.
Detailed explanation-5: -Body Waves-Primary (P) & Secondary (S) Waves. Surface Waves-Rayleigh & Love Waves.
