Question

What is Vibration?

Answer 1

1. The to and fro motion of an object about its mean position is called vibration or oscillation.
2. One complete to and fro motion of the particles of the medium about their mean position is called one oscillation or one vibration.
3. The sound travels in the form of a wave.
4. The wave starting from point L and reaching N constitutes one oscillation of the particles of the medium.
5. So, one complete oscillation constitutes a full wave.
