X-ray diffraction analysis follows which principle

Solution (By Examveda Team)

X-ray diffraction analysis is based on Bragg’s law, which states that "when the X-ray is incident onto a crystal surface, its angle of incidence θ, will reflect with the same angle of scattering θ.
It encompasses the superposition of wavefronts scattered by lattice planes, leading to a strict relation between wavelength and scattering angle, or else to the wave vector transfer concerning the crystal lattice.
