Mechanical waves need a medium to travel through. While waves can move over long distances, the movement of the medium of transmissions limited. Therefore, the oscillating material does not move far from its initial balanced position. 
Mechanical waves can be divided into three main categories according to the ways in which they travel, known as propagation. The three propagation types are longitudinal, transverse, and surface.Mechanical waves also include water waves, sound waves, earthquake waves, and much more.]]> 2017-02-28 21:54:49 UTC https://padlet.com/dani_sierra_728/r1nnqkksgwbl/wish/156879721 dani_sierra_728 https://padlet.com/dani_sierra_728/r1nnqkksgwbl/wish/156880495  Longitudinal waves is when the movement of a wave are parallel to the motion of the energy. The oscillations of a longitudinal wave are in the same direction as a wave moves. For example, you can use a slinky to describe a longitudinal wave. Instead of crests and troughs, longitudinal waves have compressions (areas where the Slinky is bunched together), and rarefactions (areas where the Slinky is spread apart). Another example of a longitudinal wave is a sound wave. Although you can't see air molecules, if you could, you would notice that sound involves air molecules hitting each other, thereby producing areas with high densities of molecules (compressions) and areas with low densities of molecules (rarefactions).]]> 2017-02-28 21:58:51 UTC https://padlet.com/dani_sierra_728/r1nnqkksgwbl/wish/156880495 dani_sierra_728 https://padlet.com/dani_sierra_728/r1nnqkksgwbl/wish/156881030 A transverse wave is one that vibrates at 90 degrees to the direction the wave is moving. For example, if you hold a Slinky between two hands and shake it up and down, you'll get a wave that moves along the Slinky, but the vibrations will still be up and down. Underwater waves, for example, are transverse.]]> 2017-02-28 22:01:56 UTC https://padlet.com/dani_sierra_728/r1nnqkksgwbl/wish/156881030 dani_sierra_728 https://padlet.com/dani_sierra_728/r1nnqkksgwbl/wish/156881534 2017-02-28 22:05:03 UTC https://padlet.com/dani_sierra_728/r1nnqkksgwbl/wish/156881534 dani_sierra_728 https://padlet.com/dani_sierra_728/r1nnqkksgwbl/wish/156882261 2017-02-28 22:10:22 UTC https://padlet.com/dani_sierra_728/r1nnqkksgwbl/wish/156882261 dani_sierra_728 https://padlet.com/dani_sierra_728/r1nnqkksgwbl/wish/156882376  A surface wave is a wave that travels along the boundary between two materials. Surface waves are classified by the type of motion they transmit. The two main types of surface waves are love waves and Raleigh waves. Love waves are are surface seismic waves that cause horizontal shifting of the Earth during an earthquake. Raleigh waves are undulating waves that travels over the surface of a solid, especially of the ground in an earthquake, with a speed independent of wavelength, the motion of the particles being in ellipses.]]> 2017-02-28 22:11:06 UTC https://padlet.com/dani_sierra_728/r1nnqkksgwbl/wish/156882376
