What are x-rays?

 

X-rays lie between ultraviolet light and gamma rays. They can pass through most substances, and this makes them very useful. I’m sure you already know that x-ray images are commonly used in medicine. An x-ray technician takes x-rays to help doctors see and diagnose diseases and injuries. X-rays are also used in airport security checks to see inside the luggage.
