It can be computed as the ratio between the link length and the propagation speed over the specific medium.

Formally, these parameters can be chosen so that the propagation speed is the speed of light.

On that occasion, the finite propagation speed of light had to be considered as well.

Slow slip events are distinguished from earthquakes by their propagation speed and focus.

Relative to a fixed time coordinate, disturbances have a finite propagation speed.

Moreover, the degree of elongation would increase with the propagation speed.

This in turn is used as a reference for describing the average propagation speed of spaceships.

Sound's propagation speed depends on the type, temperature, and composition of the medium through which it propagates.

Which leads to three characteristics, describing the propagation speed of the various regions of the system.

Effects of local actions have a finite propagation speed.
