To get the viewing distance, we observe that. s 2 π r = θ T full angle = θ T 2 π, with angle in radian. ⇒ s ( h) = r ⋅ asin ( 1 − r 2 ( r + h) 2) If you plot this for h small compared to r, it resembles a square root function, and indeed, lim h → 0 + s ( h) h = 2 r.
Ignoring the effect of atmospheric refraction, distance to the true horizon from an observer close to the Earth's surface is about where h is height above sea level and R is the Earth radius. The expression can be simplified as: where the constant equals k=3.57 km/m =1.22 mi/ft . In this equation, Earth's s… WebMay 16, 2024 · 1.22459 x 1.73205080757.
