Lesson No. 38: Linear Distribution of Velocity—II. The Refraction Time-Distance Curve
Published:January 01, 1959
To remove the difficulties mentioned in the second footnote on page 207 and 208, and, at the same time, to give further meaning to the mathematical developments and results which are of basic importance, we shall begin by examining in yet another way the initial problems implied in the integrations of the preceding Lesson.
From the meaning of the parameter p and the discussions leading to equations (2) on page 204, it is apparent that, at a point Qat depth h (see Figure 100), at which depth the seismic velocity is, of course, v(h), the angle a between the direction of the wave-path through Qand the vertical is such that

Lessons in Seismic Computing
“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.”
