🔍 Key Concepts

• Compare duration of light vs darkness for each pattern shown in the strips • Recall that on light diagrams, triangles usually mark brief flashes and long bars/blocks show periods when the light is on or off for longer • Know the definition: a flashing light is one where the light is on for a shorter time than it is off during each period

💭 Think About

• For each option, decide whether the light or the darkness takes up more of the total time in one full cycle • Identify which pattern shows short, separate pulses of light with relatively long gaps between them, instead of long steady burns or equal on/off times

✅ Before You Answer

• Be sure which symbol represents light showing and which represents darkness in these USCG-style diagrams • Confirm that in your chosen option, each individual light appearance is brief compared to the interval of darkness that follows • Eliminate any option where the light appears on as long as or longer than the dark periods, since that would be isophase or occulting, not flashing
