What is scattering?

Scattering is when something bounces around instead of going straight.

Imagine you're playing with a ball in a hallway full of pillows. When you throw the ball, it doesn't just go to the end of the hallway, it bounces off the pillows and goes all over the place. That’s like what happens with scattering: instead of moving in one direction, things bounce around in different directions.

Think about light, like from a lamp. When the light hits something like dust or tiny particles floating in the air, it doesn’t just go through, it scatters off those tiny bits and goes everywhere. That’s why you can see beams of light coming through a dusty room.

Or think of rain on a window: each drop makes the light scatter differently, making the whole scene look blurry or sparkling, depending on how the light moves around the drops.

Try this at home: take a flashlight and shine it through some milk in a glass. The tiny bits of milk make the light scatter, you’ll see the light beams clearly, like they're glowing in the air. That’s scattering in action!
