Vedclass · Accepted Answer

The wavelength of $X$-rays is of the order of interatomic spacing.

Vedclass · Answer

(A) For diffraction to occur in a crystal, the wavelength of the incident radiation must be comparable to the spacing between the atoms in the crystal lattice.Interatomic spacing in crystals is typically in the range of $1 	ext{ to } 10 	ext{ Å}$ $(10^{-10} 	ext{ m})$.$X$-rays have wavelengths in the range of $0.01 	ext{ to } 10 	ext{ Å}$, which matches the interatomic spacing.Therefore, $X$-rays are ideal for studying crystal structures through diffraction patterns.

$X$-rays are used for the structural analysis of crystals because:
