Primary waves can travel through liquids,solids and gases
secondary waves only travel through solids.
rayleigh waves are dispersive in a stratified half-space.
love waves are transverse and restricted to horizontal movement
guide questions:(answer)
1.surface waves,because it travels just below the surface of the ground.Although they move even more slowly than S-waves, they can be much larger in amplitude and are often the most destructive type of seismic wave.
2.Because,when seismic data is collected from at least three different locations, it can be used to determine the epicenter by where it intersects. Knowing this helps them calculate the distance from the epicenter to each seismograph.
