when x-rays are scattered from a crystal lattice, peaks of scattered
intensity are observed which correspond to the following conditions:
we use it to find the structural details of a crystal, if crystal structure is known we can find the wavelength by using bragg's law
The angle of incidence = angle of scattering.
The path length difference is equal to an integer number of wavelengths
That is n *lambda=2dsintheta called braggs lawwe use it to find the structural details of a crystal, if crystal structure is known we can find the wavelength by using bragg's law

Bragg's law gives the condition of strong reflection of the X rays when they are made to diffract from soild crystals. It is given as
Where
d = interplanar distance of the crystal
? = Angle made by X ray beam with the planes
? = Wavelength of X ray
n = integer
We get different angles corresponding to different n for one wavelength.
It is used to get information about the crystals like interplanar spacing and other information about the structure of the solid.

The length of a massless rod is measured using vernier callipers having 10 vernier scale divisions and least count of 0.1 mm. Two masses 1.00 ± 0.01 kg and 4.00 ± 0.02 kg are attached to its ends. If reading of vernier scale is 5 divisions coinciding with 1.3 cm, what is the % error in locating centre of mass from lighter mass
