Question 1 of 27070

When making landfall at night, the light from a powerful lighthouse may sometimes be seen before the lantern breaks the horizon. Which term describes this light?

🔍 Key Concepts

• Lighthouse range and visibility – how far a light can be seen under normal refraction conditions • The idea of seeing a glow or reflection in the sky from a powerful light source before you see the actual light • Difference between light being bent, scattered, or simply lighting up the sky above the horizon

💭 Think About

• When you are offshore at night, what do you actually see first from a very powerful coastal light: the lantern itself, or a glow in the sky above where the light is located? • Which of these answer choices sounds like a mariner’s traditional term for that first visible glow, rather than a scientific or physics term? • Think about which term would be used on a nautical chart or Light List to describe a visible glow from a distant light source before the light appears over the horizon.

✅ Before You Answer

• Check which term is commonly used in nautical publications (Light Lists, sailing directions) to describe a glow in the sky from a distant light source. • Eliminate answers that are mainly optics/physics jargon rather than seamanship or navigation terms. • Verify that the correct term refers specifically to the early, sky-glow visibility of a powerful light before it comes above the horizon.
