Seismic waves powerpoint. They are the energy that travels through the earth and recorded on seismographs. Waves and wave motion From the diagram we can see that: The distance between two consecutives nodes is /2 The distance between two consecutive antinodes is /2 The distance between an anti-node and the next node is /4 The Doppler effect is the apparent change in frequency of a wave due to the motion of the source or the observer.

Characteristics of each seismic waves. Progressive seismic waves propagate away from seismic sources. ... A colorful and comprehensive PowerPoint highlights this lesson on waves. what are seismic waves Powerpoint Presentation . P- and S-waves are referred to as body waves because they are transmitted through the volume (or body) of the material, as apposed to travelling along the surface. B 4. EVIL MATHS II If a seismic wave travels through an interface, it is similar to a ray of light passing through different media = wave refraction. Looks like you’ve clipped this slide to already.
