What is Interaction of light?

Light can bounce, pass through, or even be stopped by things it meets, that's what we call the interaction of light.

Imagine you're playing with a ball in a room full of pillows and walls. When the ball hits a wall, it bounces back, just like when light hits something and reflects off it, making us see it. That’s called reflection.

If the ball goes through a net, like in a soccer game, that's like transmission, where light passes right through something, like how you can see through a clear glass window.

Now think about a sponge, if your ball gets stuck in the sponge, that’s like absorption, where light is taken in by something and not reflected or passed through. That’s why dark colors look darker, they absorb more light!

Sometimes light hits something and changes direction, like when you shine a flashlight on a prism and it splits into rainbow colors. That's refraction.

So, light interacts with things around us all the time, just like your ball plays with pillows, walls, and sponges, it’s all part of how we see the world!
