How X-rays see through your skin - Ge Wang?

X-rays are like invisible hands that can see what’s inside your body, without touching it.

Imagine you're playing hide and seek in a room full of blankets. If someone is hiding under a blanket, you can’t see them, but if they’re under a thinner blanket, you might spot their feet or a hand. X-rays work kind of like that, but with light we can't see.

Your body has different parts: skin is soft and thin, bones are hard and thick. When x-ray "light" comes in, it goes straight through the soft parts, like your skin, but gets blocked by the harder parts, like your bones.

So when you get an x-ray picture, what you see is like a shadow show: your bones appear as white shapes on the dark background of your body. It’s like shining a flashlight in a room and seeing the shadows of furniture on the wall, only with x-rays, you're seeing inside!

You don’t feel the x-ray light, it's not like touching something warm or cold. But when it passes through your body and makes a picture, it’s like having a secret spy that can tell you what’s hiding under your skin, no touch needed!
