X-ray - Wikipedia

WebX-rays. X-rays are a form of electromagnetic radiation. They belong to the short-wavelength, high-frequency end of the electromagnetic spectrum, between the gamma and the ultraviolet radiation. They have wavelengths in the range of 10 -8 m to 10 -11 m (10nm – 0.01nm). Their frequency range is 3x10 16 Hz to 3x10 19 Hz. Webreduce by one half the number of x-ray photons passing through it. As the average energy of an x-ray beam increases, so does it HVL. The term quality refers to the mean energy of an x-ray beam. Half value layer measures the intensity of a beam. IV.
