seismic depth calculation
Seismic waves are bend when they pass through soil and rocks
beneath the earth surface, therefore
velocity changes when they pass different earth formation. All substance have
different refractive index and hence when seismic wave pass through them the
velocity changes, the waves are refracted when they cross a boundary between
types of rocks or soil formation. To pass a seismic waves through the earth a
short gun or explosive is used. The principle use the snell law and properties of echo( here reflection of
the wave) to determine the depth and spread of oil, water or any mineral deposits.
