X-Rays are powerful waves of electromagnetic energy with a short wavelength and high frequency. They are produced by bombarding cathode rays on a metal plate and used for medical, security, astronomy, industrial and restoration purposes.
Jul 1, 2024 · X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10^-8 to 10^-12 metre. The passage of X-rays through materials, including biological tissue, can be recorded.
: any of the electromagnetic radiations that have an extremely short wavelength of less than 100 angstroms and have the properties of penetrating various thicknesses of all solids, of producing secondary radiations by impinging on material bodies, and of acting on photographic films and plates as light does. 2.
An x-ray is taken when an image of internal body structures (such as bones or organs) is needed to diagnose disease or determine the extent of injuries.
Oct 5, 2018 · X-rays are types of electromagnetic radiation probably most well-known for their ability to see through a person's skin and reveal images of the bones beneath it.
