Wave - Formed when a medium experiences a self-sustaining disturbance due to a vibrating object. Waves carries energy from one point to another.Medium can either be:a) A material media (solid, liquid and gas). Waves travelling in material media are called mechanical wavesb) A field such as electromagnetic field, gravitational field and others.

When end of a stretched string being vibrated up and down, this resulting in a moving wave profile.When the string is vibrated up and down, the particles of the string oscillate at the same frequency. The oscillations is transferred to the other particles

The particles do not move with the waves. They only oscillates about their equilibrium positions.
