Q

Which is the term given to the time required for a lighted aid to complete a full cycle of light changes?

🔍 Key Concepts

• Characteristics of aids to navigation lights (e.g., flashing, occulting, isophase) • Difference between a light’s cycle of operation and how often flashes occur • How light cycles are shown on nautical charts and in Light Lists

💭 Think About

• Which choice refers to one complete sequence of light and darkness, returning to the starting point? • Think about how the U.S. Coast Guard Light List or chart notes describe a light, such as “Fl 4s” or “Iso 6s” – what does that number of seconds represent? • Which option is a standard technical term used in light descriptions, rather than a general science or everyday word?

✅ Before You Answer

• Verify which term is used in Light Lists and nautical chart legends to label the full cycle length in seconds • Check that the term you pick can describe both flashing and occulting lights, not just how many flashes per second • Eliminate any answer choices that usually describe how often something happens rather than the time for one full cycle
