vibration, or a fluctuation between two values.

A swinging, as of a pendulum. Often applied to periodic motion or variation in time of any quantity, although may mean any more or less regular variation between fixed bounds. Fluctuation is more sugg [..]

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. Familiar examples include a swinging pendu [..]

In printing technology, oscillation descibes a lateral reciprocating or oscillating motion of the ink rollers in the inking unit of a printing press.

Variation with time of a quantity. Usually implies some regularity (as in sinusoidal or complex vibration).

A to-and-fro movement.

the act of oscillating or the state of being oscillated a regular periodic fluctuation in value about some mean a single such cycle

(n) the process of oscillating between states(n) (physics) a regular periodic variation in value about a mean(n) a single complete execution of a periodically repeated phenomenon

A periodic motion backward and forward. To vibrate or vary above and below a mean value.

The variation, usually with time, of the magnitude of quantity with respect to a specified reference when the magnitude is alternately greater and smaller than the reference.

The regular movement of a body, such as balance wheel or pendulum, between two points from one extreme to the other and back again.  Anything with a regular oscillation can be used to keep time.

The travel of the balance wheel from one extreme to the other and back again.

A periodic motion backward and forward. To vibrate or vary above and below a mean value.

A respiratory support system used to remove Mucus and clear airway by oscillating Pressure on the Chest.

El Nino-Southern Oscillation or ENSO is a cycle of extreme alternating warm El Niño and Cold La Nina events which is the dominant year-to-year Climate pattern on Earth. Both terms refer to large-scale [..]

Oscillations are recurring temporal (periodic) fluctuations in variable parameters (deviations from a mean value) in a system. They occur when a system's stable state of Equilibrium is disturbed. [..]

A shift in position of various high and low pressure systems that in climate terms is usually defined as an index (i.e., a single numerically-derived number, that represents the distribution of temperature and pressure over a wide ocean area, such as the El Niño-Southern Oscillation, North Atlantic Oscillation, and Pacific Decadal Oscillation).

Back and forth movement that repeats regularly between two fixed positions.

A shift in position of various high and low pressure systems that in climate terms is usually defined as an index (i.e., a single numerically-derived number, that represents the distribution of temper [..]

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.
