🔍 Key Concepts

• Review the definition of a fixed light (a steady, uninterrupted light) versus a flashing light (very short periods of light separated by longer periods of darkness). • On light diagrams, a continuous horizontal bar usually represents a steady appearance of light, while short triangular spikes or similar marks can represent brief flashes. • Compare options where two different patterns are shown simultaneously along the same line (one steady, one intermittent).

💭 Think About

• In which option do you see a light that appears to be on all the time, with an additional pattern that shows brief, repeating flashes on top of it? • Which choices show only one type of light characteristic (all flashes or all steady blocks), and which show a combination of two different characteristics? • If the rectangles represent periods when the light is visible, which option suggests there is no complete darkness between every signal, indicating a fixed element plus flashes?

✅ Before You Answer

• Identify which diagram has a continuous baseline of light from start to finish. • Confirm that on that same line there are separate, distinct flash marks added, not gaps of darkness. • Eliminate any choice where the light is either only flashing (all separated marks with darkness between) or only fixed (a single uniform band with no flashes).
