GEOLOGY

Detailed explanation-1: -They are transverse waves, which means that the particle motion is at right angles to the direction of travel.

Detailed explanation-2: -A transverse wave is a wave in which particles of the medium vibrate at right angles, or perpendicular, to the direction that the wave travels. Another example of a transverse wave is the wave that passes through a rope with you shake one end of the rope up and down, as in the Figure below.

Detailed explanation-3: -S waves travel in the same direction, but instead of being a compressive wave, they oscillate with a shearing behavior at right angles to the direction of motion.

Detailed explanation-4: -A transverse wave causes the particles in the medium (the substance that the wave travels through) to vibrate at right angles to the direction of the wave’s motion. A cork in water and the coils of a spring are examples of this. They move up and down as the wave passes.

Detailed explanation-5: -S-waves, also known as secondary waves, shear waves or shaking waves, are transverse waves that travel slower than P-waves. In this case, particle motion is perpendicular to the direction of wave propagation.
