The wavelength of X-rays is of the order of

X-rays are electromagnetic waves with wavelengths significantly shorter than visible light, typically ranging from 0.01 to 10 nanometers [t5][t7]. In the field of X-ray diffraction and crystallography, the unit of measurement is traditionally the angstrom (Å), where 1 Å equals 10^-10 meters [t4][t9]. Specifically, X-rays used in diffraction experiments have wavelengths lying approximately in the range of 0.5 to 2.5 Å [t4]. While visible light has wavelengths in the order of 4000 to 7000 Å [t8], X-rays occupy the region between gamma rays and ultraviolet rays [t4][t6]. Other units like microns (10^-6 m) or centimeters are far too large to describe the order of magnitude of X-ray wavelengths, which are comparable to the distances between atoms in a crystal lattice [t2][t3]. Therefore, the wavelength of X-rays is of the order of 1 angstrom.
