The correct answer is: Rapid to and fro
Vibration means rapid to and fro motion motion of an object.
- Vibration is an oscillatory motion.
- The oscillation of an object moves at a point over a medium and travels back in the same path.
- So it is called a rapid to and fro motion.
- Also called periodic back-and-forth motion.
