Oscillation

Experimental Setup of Huygens synchronization of two clocks
Oscillation of a sequence (shown in blue) is the difference between the limit superior and limit inferior of the sequence.

Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. The term 'vibration' is precisely used to describe mechanical oscillation but as a synonym of 'oscillation' too. Familiar examples include a swinging pendulum and alternating current power.
