Lesson No. 5: The Elementary Seismic Reflection Problem. II
Published:January 01, 1959
In this lesson we shall deal step by step with a specific numerical case, in order to understand better the more general results in later work. We shall consider that between the surface of the earth, SS, and a plane horizontal reflecting bed, RR, whose depth is h=6,OOO ft, the medium is homogeneous and isotropic, insofar as seismic propagation is concerned, and that the speed-or velocity-is v= 7,500 It/sec. The reader is requested to draw all the pertinent relations to scale and go through with the detailed developments which follow. The exercises will pertain to the figures and results obtained.
In Figure 18, the situation described is drawn to scale and at-axis (timeaxis) is drawn through the shot-point O. The trace of the surface SS is used as an x-axis oriented positively to the right.

“An elementary text and problem book containing 44 lessons in seismology arranged for selection or combination to cover the normal 36-week course, or for condensation into an 18-week course. The lessons begin without assuming more than secondary school mathematics. An elementary knowledge of calculus is desirable, though not required, for the last half of the book.”
