Some Applications of Seismic Refraction Techniques in ...

The seismic method is divided into reflection and refraction techniques, based on whether or not a wave undergoes a reflection at the extent of its travel. Thus, while most refracted events have not been reflected, most reflected events have been refracted, because a refraction occurs across any velocity interface in accordance with the simple ...

seismic methods - refraction Everest Geophysics

The Seismic Refraction Technique is a geophysical method that benefits the refraction of seismic waves on the ground to characterize subsurface geologic conditions. The method exploits the behavior of seismic energy at interfaces with different seismic velocities. This behavior (change in direction) is described by Snell’s Law.

Principle of Geophone : Geophone Damping As geophone coil moves inside magnet, current induced in coil produces a magnetic field that opposes,i.e. damps, the movement of the coil. • If a geophone is tapped, the oscillation of coil will die out. • At critical damping, coil will return to rest most quickly.
