| As the cone begins a forward movement it generates the start of a compression wave. |
| He knew the compression wave caused by his movement would warn all living creatures. |
| Thus a compression wave will move to the end of the spring, where it will be reflected and return. |
| A high speed impact, though, will chemically mix the materials, igniting them and leading to a compression wave and significant overpressure. |
| This way, for example, inside the body the cellular membrane is broken off during the compression wave. |
| Seismic down-hole tests were performed to measure the speed of compression wave and shear wave at different layers. |
