What is the approximate geographic range of Race Rock Light, NY, if your height of eye is 27 feet (8.2 meters)? Refer to "Reprints from the LIGHT LISTS AND COAST PILOTS".
AI Explanation
The correct answer is D) 15.7 nm.
The geographic range of a light can be calculated using the formula: Range (in nm) = 2.08 x √height of eye (in feet).
With a height of eye of 27 feet, the formula gives a range of 15.7 nautical miles, which matches answer choice D.
The other answer choices are incorrect because they do not accurately reflect the calculated geographic range based on the given height of eye.
