A laser is like a super focused flashlight. It works by making light very, very tight, almost like a single line of tiny particles that all move in the same direction. Because they are all moving together, the light becomes really strong, which makes it powerful enough to do amazing things, like cutting through paper or even metal.
Examples
- A laser pointer shines a single bright dot on the wall like magic.
- A laser can cut through paper or even slice a tomato with one flash.
- Lasers are used in hospitals to remove small pieces of skin without cutting.
