An X-ray, or 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-rays are a type of radiation called electromagnetic waves. X-ray imaging is
used to create pictures of the inside of the body. The images show the parts of
the body in different shades. This is because different tissues absorb different
amounts of radiation. Most common use of X-rays are
X-ray scans are used in diagnostic devices to identify
or prevent fractures or conditions such a cancer, infections, etc.
