The correct answer is: Vibrating
When an object moves to and fro rapidly, it is said to be vibrating.
- In order to produce sound, the object creates a rapid to and fro motion i.e. oscillation.
- This oscillation travels in form of waves to a limit and travels back in the same.
- This is called vibration which is the cause of a rapid to and fro movement of the object.
