X-Ray refers to the part of the electromagnetic spectrum whose radiation has somewhat greater frequencies and smaller wavelengths than those of ultraviolet radiation; namely, that radiation lying between ultraviolet and gamma-ray in the electromagnetic spectrum.

It is a type of high-energy radiation. In low doses, x-rays are used to diagnose diseases by making pictures of the inside of the body. In high doses, x-rays are used to treat cancer.

X-ray refers to an image produced by sending a beam of X-rays - very high energy electromagnetic radiation) through the body. Different tissues in the body have different densities and absorb and deflect the X-rays differently. A camera records on photographic film the varying levels of X-rays that have passed through the body.
X-rays use invisible electromagnetic energy beams to produce images of internal tissues, bones, and organs on film. Standard x-rays are performed for many reasons, including diagnosing tumors or bone injuries.

X-rays are made by using external radiation to produce images of the body, its organs, and other internal structures for diagnostic purposes. X-rays pass through body structures onto specially-treated plates (similar to camera film) and a "negative" type picture is made (the more solid a structure is, the whiter it appears on the film).
