For a vibration to occur an object must repeat a movement during a time interval. A wave is a disturbance that extends from one place to another through space. Light and sound are vibrations that move through space — they are waves! Properties of Vibrations. A pendulum swings in a periodic motion.

What type of waves is vibration?

For a sound wave traveling through air, the vibrations of the particles are best described as longitudinal. Longitudinal waves are waves in which the motion of the individual particles of the medium is in a direction that is parallel to the direction of energy transport.

What is a vibration in physics?

vibration, periodic back-and-forth motion of the particles of an elastic body or medium, commonly resulting when almost any physical system is displaced from its equilibrium condition and allowed to respond to the forces that tend to restore equilibrium.
