oscillatable
Oscillatable is an adjective used to describe a system, object, or phenomenon that is capable of undergoing oscillation. Oscillation refers to a repetitive variation, typically in time, of some measure about a central value or between two or more different states. In simpler terms, something that is oscillatable can move back and forth, up and down, or cycle through states in a regular, recurring pattern.
Many physical systems exhibit oscillatable behavior. For example, a pendulum is oscillatable, swinging back and forth
