Lasers make super focused light. Imagine all the colors in a rainbow being stuck together and shining in one direction, like a super-powerful flashlight. This happens because lasers use tiny particles called photons that all line up to travel together, making them really strong and precise.
Examples
- Lasers are used in printers to etch ink onto paper with extreme precision.
- Dentists use lasers to remove tiny parts of your tooth without much pain.
