🔍 Key Concepts

• Geographical range vs. luminous range of a light • How height of eye and height of light combine to give total visibility distance • Using the Light List table for distance to the horizon at various heights

💭 Think About

• First, think about how to find the distance to the horizon for your 40 ft (12.2 m) height of eye using the standard table or formula. • Next, recall that the total geographical range is based on BOTH your height of eye and the light’s height above water; how are these two distances combined? • Consider what the Light List (for Ambrose Light, NY) tells you about the light’s height and how that affects the combined range.

✅ Before You Answer

• Make sure you are using geographical range, not luminous range (brightness). • Confirm you know or can look up the height of Ambrose Light from the Light List/Coast Pilot reprints. • After calculating the range from your eye and from the light, check the sum against the answer choices to see which is closest.
