Röntgen effect

The Röntgen effect refers to the phenomenon where X-rays, a type of high-energy radiation discovered by Wilhelm Röntgen, can cause certain materials to fluoresce or emit visible light when they are exposed to X-ray radiation. Essentially, when X-rays strike a suitable material, they can excite the atoms within it, resulting in the emission of light. This effect is fundamental to how X-ray imaging works in medicine and science, as it helps reveal structures inside the body or other objects by detecting the light emitted from excited materials.
