We know the ray passes through O, and we know its direction (from O to V ), so we can express any point P in the ray as P = O + t ( V − O) where t is any real number. By plugging every value of t from − ∞ to + ∞ into this equation, we get …

At any point along a ray, we can express the ray in terms of its horizontal and vertical slownesses (Figure 2), pand = cos (z) v(z) = p v2(z) p2; (3) 1 v z Increasing range (X) p decreasing (take off angle decreasing) Figure 1: Rays in media of increasing velocity with depth. Generally X increases as p decreases.
