Explain the basic principles involved in X-ray crystallography. Include Bragg's law in your explanation.

Bragg's law is considered the case of diffraction that gives coherent and incoherent angles when the ray is scattered from the crystal lattice.

Explanation:

Bragg's law is considered the case of diffraction that gives coherent and incoherent angles when the ray is scattered from the crystal lattice.

The Bragg's law is used to determine the crystal structure by explaining the scattering process between the x-ray and crystal surface.

Bagg's law stated that when incident ray incident on the surface of crystal its scattering angle will be the same as incident angle when path difference is equal to the wavelength of ray. This leads to constructive interference.
