What are light particles?

Light particles are tiny bits of energy that zoom around and make things visible, like when you see a rainbow or your favorite toy.

Imagine you're playing with marbles in the dark. When you flick one marble, it starts rolling, and poof, it lights up the room! That marble is like a light particle, called a photon. Photons are super tiny, way smaller than a grain of sand, but they carry energy just like that marble carries motion.

When you turn on a lamp, it sends out billions of these photons, and they travel through the air until they hit something, like your wall or your face. Then wham! You see light because those photons are bouncing off things and into your eyes.

You can think of them like tiny messengers: when a photon reaches your eye, it tells your brain, "Hey, there’s something over here!" And that's how you know where everything is, even in the dark.
