Explanation:
Visible Light cannot be used to study crystal structures. ... The atoms in a crystals are spaced at about 1 Angstrom apart. Visible light has a size (wavelength) of the order of 5000 Angstroms, so it cannot resolve the atoms in a crystal

Answer:
The atoms in a crystals are spaced at about 1 Angstrom apart.Visible light has a size (wavelength) of the order of 5000 Angstroms, so it cannot resolve the atoms in a crystal. It is like picking a sand grain with baking gloves. X-rays have wavelength of the same order as that of interatomic separation in a crystal. That means Crystal structures are determined using X-rays as probes.
