WebP waves are like the lightning, and S waves are like the thunder. The P waves travel faster and shake the ground where you are first. Then the S waves follow and shake the ground … WebS- or secondary-waves are slower than P-waves, arriving shortly after a P-wave at a seismic station. All wave types travel faster through, denser and more rigid mediums, however, S-waves can only travel through solid materials while P-waves can travel through materials in a solid, liquid, or gaseous state.
