How Mirrors Work

Mirrors reflect light. This means they bounce light back. The light travels in a straight line. A mirror sends it in a new direction. This is why you can see yourself. The light from your body bounces off the mirror. Then it comes back to your eyes.

Concentration of Light

Some mirrors can focus light. These mirrors are curved. They are called concave mirrors. Concave mirrors can concentrate light in one spot. This spot is called the focal point. The light is very strong at the focal point.

Starting a Fire with a Mirror

If you place something flammable at the focal point, it can catch fire. Flammable materials burn easily. They include paper, dry leaves, and cloth. The concentrated light heats the flammable material. If it gets hot enough, it will start to burn.

Let’s look at an example. Imagine you have a concave mirror. You place it in the sun. The mirror focuses the sunlight. The light hits a piece of paper. The paper starts to smoke. Soon, it catches fire.

Real-Life Incidents

There have been real cases of fires started by mirrors. One famous case happened in London. A building caught fire. Investigators found the cause. It was a glass ornament. The glass focused the sunlight. It hit a curtain. The curtain caught fire. The fire spread to the whole building.
