The Gibb’s Hill Lighthouse, Southampton, Bermuda . In Operation since 1846 , stands 117 feet high on a hill 245 feet high, so its beam of light is 362 feet above sea level. A brochure states that the light itself can be seen on the horizon about 26 miles distant. Verify the accuracy of this information. The brochure further states that ship 40 miles away can see the light and the planes flying at 10 , 000 feet can see it 120 miles away. Verify the accuracy of these statements. What assumption did the brochure make about the height of the ship?
