Introduction to Vibration and Waves
Introduction
Basically, anything that moves back and forth, side to side, or up and down is vibrating.
- A vibration is a periodic wiggle in time. Periodic means the pattern repeats itself with time.
- A wave is a periodic wiggle in both space (distance) and time, and
- a wave is a moving vibration.
Examples of water waves and loudspeaker vibrations are illustrated below:
