A laser is like a flashlight that makes light super strong and super focused. Imagine you're in a room full of people all clapping at the same time, they make a loud sound because everyone is doing the same thing together. A laser works similarly: lots of tiny particles called photons all move in the same direction, making one very bright beam of light. This makes lasers useful for things like cutting paper, helping doctors see inside your body, and even sending signals to space!
Examples
- A laser pointer shines a bright red dot on a wall like magic.
- A laser in a barber shop helps the barber cut hair very precisely.
- A laser in a printer makes the ink stick to paper perfectly.
