How Does a ‘Laser’ Work and What Is It Used For?

A laser is like a super-focused flashlight. It sends out light in one straight line, like a beam of magic that can cut through things or make pretty lights on stage. Imagine all the light from your flashlight being squeezed into one tiny point, that’s how lasers work! They are used for things like scanning barcodes, making surgery easier, and even playing games!
