Question: is an x ray a photon?
Answer: Photons are called x-rays if they are produced by electron interactions. An x-ray photon has a wavelength of 0.01 to 10 nanometers, with a frequency of 3×1016 Hz to 3×1019 Hz. ... The wavelength of a photon is identical to the wavelength of the electromagnetic wave it is described to be a part of.
