There are also three main types of Mechanical waves, transverse waves, longitudinal waves, surface waves. media type="custom" key="5864045"

__**Longitudinal waves**__
Definition: Waves in which the vibration of the medium is parallel to the direction the wave travels. Examples: Waves in springs, P waves



__**Transverse waves**__
Definition: Waves in which the vibration of the medium is in right angles to the direction the wave travels Examples: Shaking a picnic blanket to get crumbs off, T waves

__**Surface waves**__
Definition: A wave that travels along surface separating two media Examples: Buoy in the ocean staying in one place, S waves
