Webb5 apr. 2024 · X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10−8 to 10−12 metre and corresponding frequencies from about 1016 to 1020 hertz (Hz). X-rays are commonly produced by accelerating (or decelerating) charged particles; examples include a beam of electrons … WebbAn x-ray beam contains many x-rays that possess only very low energy, which will contribute nothing to the x-ray image and will only increase the radiation exposure to the patient. They are too weak to penetrate through body tissues and interact with the film or image receptor.
