Visual Line of Sight Calculations dependent on Earth's Curvature

 

We are told, the supposed ball Earth has a radius of approximately 3965 miles. Using the Pythagorean theorem, that calculates to an average curvature of 7.98 inches per mile or approximately 8 inches per mile (squared). The distance to the horizon in miles from height of an observer is approximately equal to 1.23 times the square root of the height in feet. For example 1.23 times the square root of 8 divided by 12 equals 1 mile. Inversely given the horizon distance in miles, the height in feet required to be visible equals the distance in miles squared divided by 1.513.

If a Lighthouse is 264 ft tall it should disapear at 20 miles

Yet many lighthouses can still be seen at over 120 miles

away, when the atmospheric conditions are good.
