X ray is the oldest kind of imaging technology.
What kind of energy is an x ray.
Examples include a beam of electrons striking a metal plate in an x ray tube and a circulating beam of electrons in a synchrotron particle accelerator or storage ring in addition highly excited atoms can emit x rays with discrete wavelengths characteristic of the energy level spacings in the atoms.
X rays can be produced on earth by sending a high energy beam of electrons smashing into an atom like copper or gallium according to kelly gaffney director of the stanford synchrotron radiation.
Less hard substances like muscles let more of the rays through so they show up as gray or black.
An x ray or x radiation is a penetrating form of high energy electromagnetic radiation most x rays have a wavelength ranging from 10 picometres to 10 nanometres 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 124 ev to 124 kev x ray wavelengths are shorter than those of uv rays and typically longer than those of.
