The term "harmonic oscillator" is used to describe any system with a "linear" restoring force that tends to return the system to an equilibrium state. There is both a classical harmonic oscillator and a quantum harmonic oscillator. Both are used as toy problems that describe many physical systems.

Frequency of driven damped oscillation and the driven force
For a driven damped oscillation, if the driven force $F = F_0 \cos(\omega t)$, then the solution to the motion is
$$x = A \cos(\omega t+\varphi ) \, .$$
Why must the the oscillation and the driven f …
