The method developed by the Braggs (William and his son Lawrence, who later
jointly won the Nobel Prize) is the foundation of almost all modern work in X-ray
crystallography. They used a single crystal and a monochromatic beam of X-rays, and
rotated the crystal until a reflection was detected. There are many different sets of
planes in a crystal, so there are many angles at which a reflection occurs. The complete
set of data consists of the list of angles at which reflections are observed and their
intensities.

n/|=2d sino       n=order ofdiffraction,/|=wavelength of X-rays,d=distance btw two layers,o=angle of diffraction
 
W.H.Bragg proposed this equation obtain a relation btw /\,n,d,o.

Braggs law;
It states that the extra distance travelled by a wave is directly proportional to the wavelenght
2dsin θ = nλ
d=interplanar distance
 θ=angle of incidence
λ=wavelength

When x-rays are scattered from a crystal lattice, peaks of scattered intensity are observed which correspond to the following conditions: The angle of incidence is equal to angle of scattering. The pathlength difference is equal to an integer number of wavelengths.
