3、 dictionary defines a wave as “a disturbance or variation that transfers energy progressively from point to point in a medium and that may take the form of an elastic deformation or of a variation of pressure, electric or magnetic intensity, electric potential, or temperature.“ The most important pa
4、rt of this definition is that a wave is a disturbance or variation which travels through a medium. The medium through which the wave travels may experience some local oscillations as the wave passes, but the particles in the medium do not travel with the wave. I-Shou University C.S.

5、Body Waves and Surface WavesBody Waves travel through the interior of the Earth.P, Primary, or Compressional waves travel the fastest (6 km/sec in the upper crust).S, Secondary, or Shear waves are somewhat slower (3.5 km/sec in the upper crust).http:/www.ndt-ed.org/EducationResources/CommunityColleg
