An X-ray is a form of electromagnetic radiation with a wavelength approximately in the range of 5 pm to 10 nanometers (corresponding to frequencies in the range 30 PHz to 60 EHz). For their ability to penetrate skin (but not bone), they have found extensive usage in medical and anatomical contexts.
