Vertical resolution is estimated as z/4, where is the dominant wavelength: V/f. Reflection frequencies decrease with depth because of attenuation of seismic waves, and this also decreases the resolution at depth. I know there is more behind this, but I just want to know if this basically is the difference? Because I am not sure of that. Seismic resolution is controlled by the bandwidth of the signal, which is typically f30-140 Hz. So, you need to use different places for your seismographs in order to get the refracted waves, which are further away from the source than the reflected waves. Seismic reflection/refraction imaging has successfully been used in the oil industry to detect buried hydrocarbon traps for about 85 years (Dobrin, 1976). question is that the incident ray is a Pwave and the reflected ray is. In refraction seismology, you want the waves to get into the next layer and as you know that there are different velocities in different layers, that is how you get information out from there (detail here on how that works not of interest right now). interface at a 45.0 angle with a rock velocity of 4.00 km/s on the other side. Thereby you would get a much smaller space in which waves would get back to the surface. Now reflection seismology tries to get information from the reflected waves the ones, that do not get into another layer but get reflected from it r get directly through the layer and get reflected by the next. Both methods use explosives to send waves into the earth's surface. So I am wondering if I got the difference right. I present results of processing and structural interpretation of narrow-angle seismic reflection data recorded over an area of 30 × 50 km located in the.
