Definition
| are primary waves (compressional) they travel through solid, liquid, or gaseous material as a succession of compression and expansions. |
|
|
Term
|
Definition
| secondary waves (shear) they displace material at right angles to their path of travel. they do not exist in liquid or gases. |

Term
| What are the different motions of P and S waves? |
|
Definition
| The P waves move in a compressional motion similar to the motion of a slinky, while the S waves move in a shear motion perpendicular to the direction the wave is travelling. |
