Web9 de jan. de 2010 · distance to horizon (miles) = √ 7h (feet)/4 This formula gives you the rough distance (Imperial) of the apparent horizon accounting for normal refraction. This is the distance to where the sky appears to meet the Earth. If mirages are apparent, the distance to the apparent horizon may differ. Web31 de jan. de 2024 · The horizon at sea level is approximately 4.5 km. To calculate it, follow these steps: Assume the height of your eyes to be h = 1.6 m. Build a right triangle with hypotenuse r + h (where r is Earth's radius) and a cathetus r. Calculate the last cathetus with Pythagora's theorem: the result is the distance to the horizon: a = √ [ (r + h)² - r²]

WebSo feet and So Milong can see about 4.7 miles out on the ocean when standing on a 10-foot lifeguard tower. When Milong is standing at the top of Mount Shishaldin (9373 feet), the steps are the same as parts (a) and (b) with a change in height , which is now the height of Milong plus the height of Mt. Shishaldin. Due to atmospheric refraction the distance to the visible horizon is further than the distance based on a simple geometric calculation. If the ground (or water) surface is colder than the air above it, a cold, dense layer of air forms close to the surface, causing light to be refracted downward as it travels, and therefore, to some extent, to go around the curvature of the Earth. The reverse happen… Web12 de jan. de 2024 · So here’s the math. For a 170cm tall observer standing on the ground, the horizon is at a distance of 4.7 kilometres. The 2 metres tall person standing in the same place would see as far as 5 kilometres. If an observer climbed up 100 metres above sea level, the horizon would be at a distance of 36 kilometres.
