Oscillation refers to a repetitive variation, typically in time, of some measure about a central value or between two or more different states. This phenomenon is ubiquitous in nature and technology, appearing in systems ranging from the microscopic world of atoms to the macroscopic scale of celestial bodies. A fundamental characteristic of an oscillation is its period, which is the time it takes for the system to complete one full cycle of its motion. The frequency, conversely, is the number of cycles that occur per unit of time, and it is the inverse of the period. The amplitude describes the maximum displacement or extent of the oscillation from its equilibrium position.

Simple harmonic motion is a particularly important type of oscillation where the restoring force is directly proportional to the displacement from equilibrium. This idealized motion is characterized by a sinusoidal waveform. Many real-world oscillations can be approximated as simple harmonic motion, especially when the displacements are small. However, most oscillating systems are subject to damping, a force that opposes the motion and causes the amplitude to decrease over time. If energy is continuously supplied to an oscillating system, it can exhibit resonance, where the amplitude becomes very large when the driving frequency matches the system's natural frequency. Examples of oscillations include the swinging of a pendulum, the vibration of a string on a musical instrument, the alternating current in electrical circuits, and the oscillations of atoms in a crystal lattice. Understanding oscillations is crucial in fields such as physics, engineering, and biology for analyzing and designing systems.
