WebImportant Equations. To find the distance from the observer's eye to the horizon (d1) we first perform the following: 1. d1 = sqrt(h0^2 + 2 * R * h0) Next, we place d1 in the … WebNOTE: If the observer is in a duct, the ray curvature exceeds the Earth's curvature; so k becomes greater than unity. That makes this equation for d 2 negative. Physically, what happens is that any ray that can reach the observer's eye meets the surface at an angle; there's no horizon at all, in the sense of a ray that is tangent to the surface.
