How Does a Mirror Reflect Our Image Back to Us?

Imagine you're a ball of light bouncing around inside your body. When you look in the mirror, it's like your light bounces off your face and then goes back to your eyes, only now it looks like it came from behind the mirror. Mirrors work by reflecting light, just like a super-smart bounce-back game. The image you see is a copy of yourself, flipped left-to-right, because that's how the light travels: in straight lines and equal angles.
