An X-ray, or, much less commonly, X-radiation, is a penetrating form of high-energy electromagnetic radiation. Most X-rays have a wavelength ranging from 10 picometers to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz and energies in the range 124 eV to 124 keV. X-ray imaging creates pictures of the inside of your body. The images show the parts of your body in different shades of black and white. … The most familiar use of x-rays is checking for fractures (broken bones), but x-rays are also used in other ways
