orx-ray
n
1. (General Physics)
a. electromagnetic radiation emitted when matter is bombarded with fast electrons. X-rays have wavelengths shorter than that of ultraviolet radiation, that is less than about 1 × 10–8 metres. They extend to indefinitely short wavelengths, but below about 1 × 10–11 metres they are often called gamma radiation
b. (as modifier): X-ray astronomy.
2. (Medicine) a picture produced by exposing photographic film to X-rays: used in medicine as a diagnostic aid as parts of the body, such as bones, absorb X-rays and so appear as opaque areas on the picture
3. (Photography) a picture produced by exposing photographic film to X-rays: used in medicine as a diagnostic aid as parts of the body, such as bones, absorb X-rays and so appear as opaque areas on the picture

x-ray
also X-ray (ĕks′rā′)1. A high-energy stream of electromagnetic radiation having a wavelength shorter than that of ultraviolet light but longer than that of a gamma ray. X-rays are absorbed by many forms of matter, including body tissues, and are used in medicine and industry to produce images of internal structures. See more at electromagnetic spectrum.
2. An image of an internal structure, such as a body part, taken with x-rays.
