Secondary waves are also called S waves.
As they pass through a material, the material’s particles are shaken up and down or from side to side.
Secondary waves rock small buildings back and forth as they pass.
Secondary waves can travel through rock, but unlike primary waves they cannot travel through liquids or gases.
How do secondary waves travel?
Secondary waves (also called shear waves, or S waves) are another type of body wave. They move a little more slowly than P waves, and can only pass through solids. As S waves move, they displace rock particles outward, pushing them perpendicular to the path of the waves.
What can P waves travel through?
The P wave can move through solid rock and fluids, like water or the liquid layers of the earth. It pushes and pulls the rock it moves through just like sound waves push and pull the air.
What is the meaning of secondary waves?
The definition of an S wave, or secondary wave, is a wave motion in a solid medium where the medium moves perpendicular to the direction of the travel of the wave. An example of an S wave is when pieces of rock in an earthquake vibrate at right angles to the direction of the seismic wave.
What are primary and secondary waves?
Primary waves travel faster, move in a push-pull pattern, travel through solids, liquids and gases, and cause less damage due to their smaller size. Secondary waves travel slower, move in an up-and-down pattern, travel only through solids, and cause more damage due to their greater size.
