Reflection seismology ( or seismic reflection ) is a method of exploration geophysics that uses the principles of seismology to estimate the properties of the Earth's subsurface from reflected seismic waves.

In common with other geophysical methods, reflection seismology may be seen as a type of inverse problem.

In the case of reflection seismology, the experimental data are recorded seismograms, and the desired result is a model of the structure and physical properties of the Earth's crust.

In common with other types of inverse problems, the results obtained from reflection seismology are usually not unique ( more than one model adequately fits the data ) and may be sensitive to relatively small errors in data collection, processing, or analysis.

A method similar to reflection seismology which uses electromagnetic instead of elastic waves, and has a smaller depth of penetration, is known as Ground-penetrating radar or GPR.

The use of reflection seismology in studies of tectonics and the Earth's crust was pioneered in the 1970s by groups such as the Consortium for Continental Reflection Profiling ( COCORP ), who inspired deep seismic exploration in other countries such as BIRPS in Great Britain and ECORS in France.

Many other companies using reflection seismology in hydrocarbon exploration, hydrology, engineering studies, and other applications have been formed since the method was first invented.

The principles involved are similar to reflection seismology, except that electromagnetic energy is used instead of acoustic energy, and reflections appear at boundaries with different dielectric constants instead of acoustic impedances.

* Root Mean Square ( RMS ) stacking velocities which are derived from the processing of the seismic reflection data

This is known as a Common Midpoint Gather ( a midpoint being the area of the subsurface that a seismic wave reflects off before returning to the receiver ) and in a typical seismic reflection processing workflow, the average amplitude would be calculated along the time sample, in a process known as “ stacking ”.

If the world is reflected in a mirror which switches the left and right side of the car, the reflection of this angular velocity vector points to the right, but the actual angular velocity vector of the wheel still points to the left, corresponding to the minus sign.

This linear growth is a reflection of the momentum uncertainty: the wavepacket is confined to a narrow width √ a, and so has a momentum which is uncertain ( according to the uncertainty principle ) by the amount ħ / 2 √ a, a spread in velocity of ħ / 2m √ a, and thus in the future position by ħt / m √ a.

* Light retains throughout its whole path the component of velocity which it obtained from its original moving source, and after reflection light spreads out in spherical form around a center which moves with the same velocity as the original source.

for a target moving with constant radial velocity v. The reflection of the signal is represented with compression ( or expansion ) in time by the factor ', which is equivalent to a compression by the factor ' in the frequency domain ( with an amplitude scaling ).

Depth conversion is an important step of the seismic reflection method, which converts the acoustic wave travel time to actual depth, based on the acoustic velocity of subsurface medium ( sediments, rocks, water ).

This form of the equations allows one to see the effects of density and P-or S-wave velocity variations on the reflection amplitudes.

If the velocity, acquired by the particle as the result of the above reflection law, is directed to the interior of the domain, then the particle will leave the boundary and continue moving in until the next collision with.
