But when feet feel cold but are not cold to the touch, a possible cause is a neurologic problem, such as peripheral neuropathy. Of course, feet can get cold for many reasons. The most obvious is a cold environment, along with a lack of proper shoes or socks.
X-RAY PHOTON. A brief definition of an x-ray photon was previously stated. However, a more comprehensive definition is necessary for the next series of photon actions. X-ray photons are electromagnetic rays produced in the x-ray tube head when electrons from the cathode filament strike the anode target. They are bundles of pure energy. The photons transfer their energy to the substance through which they pass whether it be air, an x-ray film, or the living tissue of the patient or the specialist. They cannot be seen or felt. a. Photon Action Upon Atoms. (1) Photon collision with the nucleus of an atom. The photon may strike the nucleus of an atom.
Report Abuse. X-radiation (composed of X-rays) is a form of electromagnetic radiation. X-rays have a wavelength in the range of 0.01 to 10 nanometers, corresponding to frequencies in the range 30 petahertz to 30 exahertz (3 Ã 1016 Hz to 3 Ã 1019 Hz) and energies in the range 120 eV to 120 keV.hen x-rays were first discovered, scientists didn't know much about them, so they called them X-rays because X in science is often used to designate an unknown as in Planet X or solve for X They were also sometimes called Rontgen Rays after the man who discovered them.
