WebIn a copper X-ray spectrum, it produces 3 characteristic lines, Kα1, Kα2, and Kβ. In general, Kα is observed as a doublet peak in the XRD pattern and Kβ is fileted out by a metal foil … WebIf diffraction and interference occurs when the wavelength of light is a similar size to the width of the slit of an optical grating, and if X-rays were indeed waves that have a wavelength at least ten thousand times shorter than visible light, then in theory the spaces between the atoms in a crystal might be just the right size to diffract X-rays.
