WebThe curvature of the earth means that a line of sight that is horizontal at the instrument will be higher and higher above a spheroid at greater distances. The effect may be insignificant for some work at distances … WebThe curvature of the earth has been the limiting factor of lines of sight. As two objects get further apart, the earth will obstruct the LOS between them. Eventually it will disappear …
WebNov 18, 2024 · The fact that the curvature isn't "eradicated" by this refractive model can pretty simply be verified by realizing that light still has to travel a distance longer (and hence, for a time measurably longer) than the straight connection between the points. So, yes, I'd consider that answer wrong. WebApr 9, 2015 · The earth is a sphere about 4000 miles in diameter. 100 miles is 1/40 of the radius. By similar triangles, a horizontal line 100 miles long would be 100/40 or 2.5 miles high at 100 miles. So the clouds would …
