WebAug 2, 2024 · Oscillation refers to the repeated back and forth movement of something between two positions or states. An oscillation can be a periodic motion that repeats itself in a regular cycle, such as a sine wave —a wave with perpetual motion as in the side-to-side swing of a pendulum, or the up-and-down motion of a spring with a weight.
