An oscillation is a periodic motion that repeats itself in a regular cycle.
- Oscillation is a characteristic of waves, including electromagnetic waves.
- Examples of oscillation include the side-to-side swing of a pendulum and the up-and-down motion of a spring with a weight attached.
- Electromagnetic waves oscillate due to the transmission of energy by their electric and magnetic fields.
- An oscillating movement is typically around a point of equilibrium and the motion repeats itself around an equilibrium position.
