oscillation

Oscillation refers to a repetitive back-and-forth movement around a central point or equilibrium position. This pattern occurs in many systems, such as a pendulum swinging, a guitar string vibrating, or electrical signals in circuits. The motion follows a regular cycle, with the system moving away from and returning to its starting point. Oscillations are fundamental in nature and technology, helping us understand phenomena like sound waves, light waves, and mechanical vibrations. The key idea is continuous, predictable movement centered around a stable position, which can be characterized by properties like frequency, amplitude, and period.
