Oscillation refers to the repetitive back-and-forth movement of an object or system around a central point. This can be seen in everyday examples like a swinging pendulum or a vibrating guitar string. The motion can be regular, like the steady rhythm of a metronome, or irregular, depending on the forces acting on the object. In physics, oscillation is often described in terms of frequency and amplitude. Frequency indicates how many times the object moves back and forth in a given time, while amplitude measures the maximum distance from the central point. Understanding oscillation helps explain various phenomena, from sound waves to the behavior of springs.
