FIG. F-26. Fresnel-zone nomogram. A straight line connecting two-way traveltime and the frequency intersects the central line at the same point as a straight line connecting the velocity and the radius of the zone. For example, a 20-Hz reflection at 2.0 s and a velocity of 3.0 km/s has a Fresnel zone radius of 470 m.
