    ** How Are X-rays Made? **

  X-rays are produced when electrons strike a metal target. The
electrons are liberated from the heated filament and accelerated by a high
voltage towards the metal target. The X-rays are produced when the
electrons collide with the atoms and nuclei of the metal target.

X-rays are part of the electromagnetic spectrum, with wavelengths shorter
than visible light. Different applications use different parts of the X-ray
spectrum.

*X-radiation* (composed of *X-rays*) is a form of electromagnetic
radiation. Most X-rays have a wavelength ranging from 0.01 to 10
nanometers, corresponding to frequencies in the range 30 petahertz to 30
exahertz (3×10^16 Hz to 3×10^19 Hz) and energies in the range 100 eV
to 100 keV. X-ray wavelengths are shorter than those of UV rays and
typically longer than those of gamma rays. In many languages, X-radiation
is referred to with terms meaning *Röntgen radiation*, after Wilhelm
Röntgen,^[1] who is usually credited as its discoverer, and who had
named it /X-radiation/ to signify an unknown type of radiation.^[2]
Spelling of /X-ray(s)/ in the English language includes the variants
/x-ray(s)/, /xray(s)/, and /X ray(s)/.^[3]

X-rays with high photon energies (above 5–10 keV, below
0.2–0.1 nm wavelength) are called /hard X-rays/, while those with
lower energy are called /soft X-rays/.^[4] Due to their penetrating
ability, hard X-rays are widely used to image the inside of objects, e.g.,
in medical radiography and airport security. The term /X-ray/ is
metonymically used to refer to a radiographic image produced using this
method
