How Do Lighthouses Work?

Lighthouses are like super tall flashlights that help ships find their way at night or when it’s foggy.

Imagine you're playing a game of hide and seek in the dark, and someone turns on a flashlight to show you where they are. That’s what lighthouses do, they shine a strong light so boats can see them and know where they are.

A lighthouse has a special kind of lamp inside it called a light source, which is like a really bright bulb. This light shines out through a big window or lens at the top of the tower, just like how your flashlight beam comes out from the front.

Sometimes, the light spins around, this makes the light blink on and off in a pattern, so ships can tell they’re getting close to the shore.

Ships use the lighthouse’s light as a guide, just like you might follow a friend’s flashlight beam through the woods. The closer the ship gets, the bigger the light looks, helping the sailors know when to slow down or change direction.

So next time you see a lighthouse glowing in the distance, remember, it's just a very tall, very bright flashlight helping ships find their way home!
