Harmonic Oscillator

A harmonic oscillator is a system that experiences repetitive motion around an equilibrium point, like a swinging pendulum or a mass on a spring. When displaced from its original position, it naturally tends to return due to a restoring force, leading to oscillations. These movements occur at a specific frequency, determined by the system's properties like mass and stiffness. Harmonic oscillators are fundamental in physics and engineering, appearing in various contexts such as sound waves, electrical circuits, and molecules, illustrating how energy moves back and forth in a predictable, orderly manner.
