Oscillations are called processes in which the movements or states of a system are regularly repeated in time. The oscillation period T is the period of time through which the state of the system takes the same values: u (t + T) = u (t). A wave is a disturbance (a change in the state of the medium) that propagates in space and carries energy without transferring matter. The most common are elastic waves, waves on the surface of a liquid, and electromagnetic waves. Elastic waves can only be excited in a medium (gas, liquid, solid), and electromagnetic waves propagate in a vacuum.

The angle of rotation of the point around the circle with uniform rotation is proportional to time. Accordingly, the phase of harmonic oscillation is the angle corresponding to time.
