Understanding the Period of Lighthouse Patterns

Lighthouses play a crucial role in guiding sea ships at night with their unique light beacon patterns. By identifying the period of these patterns, we can extend the diagrams accurately. In this mathematics unit, we delve into determining the period of a lighthouse pattern based on its alternating light flashes and dark periods, aiding in navigation and safety at sea.

1. Mathematics Unit 43: Lighthouse Lighthouses are towers with a light beacon on top. Lighthouses assist sea ships in finding their way at night when they are sailing close to the shore. A lighthouse beacon sends out light flashes with a regular fixed pattern. Every lighthouse has its own pattern. In the diagram below you see the pattern of a certain lighthouse. The light flashes alternate with dark periods. It is a regular pattern. After some time the pattern repeats itself. The time taken by one complete cycle of a pattern, before it starts to repeat, is called the period. When you find the period of a pattern, it is easy to extend the diagram for the next seconds or minutes or even hours.
