What is the approximate geographic range of Shinnecock Light, NY, if your height of eye is 24 feet (7.3 meters)? Refer to "Reprints from the LIGHT LISTS AND COAST PILOTS".
AI Explanation
The correct answer is D) 15.9 nm.
The geographic range of a light can be calculated using the formula: Range (in nautical miles) = 2.23 x √height of eye (in feet). With a height of eye of 24 feet, the calculation is: 2.23 x √24 = 15.9 nm. This is the formula provided in the "Reprints from the LIGHT LISTS AND COAST PILOTS" reference material.
The other options are incorrect because they do not accurately reflect the calculated range based on the given height of eye. Option A (8.7 nm) and B (9.9 nm) are too low, while option C (14.4 nm) is also an incorrect value.
