X-ray

X-rays are like invisible light beams that can pass through soft things like your skin and muscles, but they get stopped by harder things like your bones. When they pass through you, they make a special picture on a screen or film. It’s like a secret message from inside your body!

Doctors use these pictures to see if your bones are broken or if something else is going on inside you. They are super useful for helping people get better.

A very smart scientist named Wilhelm Röntgen discovered X-rays by accident in 1895. He was playing with special glass tubes and electricity. Suddenly, he noticed a glow on a screen nearby, even though the tube was covered! He realized he had found a new kind of invisible ray. He called them 'X-rays' because 'X' means unknown. It was like finding a hidden treasure in science!

X-rays are like magic windows for doctors. They help doctors see inside your body to find out what's wrong. If you fall and hurt your arm, an X-ray can show if your bone is broken. This helps the doctor fix it so you can play again soon! X-rays are also used in airports to check bags and in science to look at rocks and even stars. They help us understand the world better.

Imagine shining a flashlight through your hand. You can see the shadow of your bones, right? X-rays work a bit like that, but they are invisible.

When X-rays go through your body, your bones block more of them than your skin. The X-rays that get through hit a special plate, making a picture. Where the bones blocked the X-rays, the picture is white.

Where the X-rays passed through easily, the picture is dark. It’s a clever way to see inside!
