WebFeb 4, 2024 · For a six-foot-tall person, the curvature is approximately 3 miles away. This is a geometrical finding since the human eye cannot see a 72-inch curve from 3 miles away. Studies place the threshold altitude for seeing Earth's curvature at about 35,000 feet. http://mathcentral.uregina.ca/QQ/database/QQ.09.97/dyck2.html
WebUsing the theorem of Pythagoras a 2 = 3963 2 + 1 2 = 15705370 and thus a = 3963.000126 miles. Thus your position is 3963.000126 - 3963 = 0.000126 miles above the surface of the earth. 0.000126 miles = 12*5280*0.000126 = 7.98 inches. Hence the earth's surface curves approximately 8 inches in one mile. Look at our response to Shirley to see what ... WebThus the Earth curves 1/12742 = 0.00007848 km = about 8 cm after 1 km. This approximation can be used because the limit of the pythagorean relation sqrt (r² + d²) as d approaches zero is r + d²/2r. Limit calculations …
WebFeb 13, 2024 · To calculate the radar horizon, take the height of the radar system h, and feed it into the equation: d=√ (2 × Rₑ × h), where: Rₑ is the Earth's radius; and. d is the radar horizon. To consider atmospheric refraction, you must multiply the expression under the square root by an additional factor of 4/3. WebDec 21, 2024 · The Earth’s curvature explains this phenomenon, as described in the diagram accompanying the photograph. The Earth’s curvature is also visible laterally in …
