Medium effects on waves Geometrical spreading

Medium effects on waves Geometrical spreading. Wave spreads over a larger surface as it travels through the medium. For a spherical wave, the wave energy falls off as the square of the distance. Its effect is to weaken the later arrivals in the seismic section.
