Feb 27, 2024 · Visible light photons and X-ray photons are both produced by the movement of electrons in atoms. Electrons occupy different energy levels, or orbitals, around an atom's nucleus. When an electron drops to a lower orbital, it needs to release some energy -- it releases the extra energy in the form of a photon.
An x-ray machine is like a giant camera that allows doctors to see what is going on inside a patient without having to do surgery. It took a long time for scientists to make the x-ray safe for medical use. Today’s x-ray machines produce a stream of electromagnetic radiation that interacts with an anode in an x-ray tube. The x-rays made by ...

Imagine you had the job of redesigning lightto make it a bit more powerful—so you couldsee through bodies, buildings, and anything else you fancied. You might come up with something a bit like X rays. X rays are a kind of super-powerful version of ordinary light: a higher-energy form ofelectromagnetic radiation that travel at the speed of lightin s...
From studying tooth decay in your mouth to detecting events in distant galaxies, X rays are useful in many different ways.
If you've read our main article on light, you'll understand that you see things whenthey reflect light rays. More specifically, reflection happens whenthe electrons in atoms inside objects move position to absorb and then re-emit lightenergy. If you want to make red light, you can shine a flashlight ona tomato so the red part of the original white ...

X-rays. X-rays are powerful waves of energy. Like light, X-rays are a form of radiation. They are very useful because they can go through substances that light cannot. X-rays can show images, or pictures, of the inside of an object, such as a suitcase or the human body. An X-ray machine makes X-rays and directs them toward an object.
X-rays are potentially hazardous. Hospital staff have a duty to use X-rays responsibly. This tutorial describes how X-rays are produced and how they interact with the body in forming a radiographic image. X-ray safety issues are briefly discussed. A basic knowledge of X-ray physics is complementary to knowledge of X-ray interpretation.
