Their wavelength is smaller the UV rays and they are therefore invisible to the human eye. They also ran into the glass of the tube and two special parts of the tube called the cathode and anode. Not only had Roentgen discovered x-rays, he saw firsthand (pun intended!) We encourage you to read the text above carefully to learn how x-rays work!

This property makes it possible to use X-ray equipment to create an image of the human body that allows a physician to get a look at what is happening inside without the need for an invasive procedure. White areas show where denser tissues, such as bones, have absorbed the x-rays. X-rays are able to penetrate through non-metallic materials. SCIENCE — Physical Science. Thanks, Wonder Friend! Instead, they help doctors find ways to make you feel better. The good thing was there was no broken bones. Doctors can also record the moving X-ray images on film or video.
