A laser is like a super-focused flashlight that sends out all the same colors of light in a straight line. Imagine if you had a bunch of identical red balls all moving together, that's kind of how a laser works! It’s super useful because it can cut through things, help doctors see inside your body, or even send messages across space.
Examples
- A laser pointer is like a tiny flashlight that can light up the whole room from far away.
- Doctors use lasers to remove small pieces of skin without making big cuts.
- A laser in a barcode scanner reads the lines on a product's label really quickly.
