How to solve these two questions in detailed solution?

To the right is a depiction of a sodium chloride crystal structure. Given the density of NaCl to be 2.16 g/cm^3 and the atomic mass unit, u, to be 1.66x10'-27 kilograms, calculate the lattice spacing of the crystal. The sodium chloride crystal is used in a Brag spectrometer to measure the wavelength of a particular X-ray source. The spectrometer detects scattered X-rays produced by born barding molybdenum with high energy electrons, and this metal is known to have two characteristic emission peaks, the K alpha and K beta lines, at 71.08 and 63.09 picot meters (pm), respectively. At what scattering angles of will these peaks be detected? In a particular Compton experiment. X-rays are scattered from free electrons with and the wavelength at a scattering angle of 90 degree s are measured to be 56.0 pm. If same X-rays were scattered from free protons, what would be the measured scattered wavelength?

Explanation / Answer

To calculate the lattice spacing first we have to calculate the Lattice Constant using the formula

A=

A=

A=5.63A

For cubic symmetry Lattice spacing

d = a/sqrt(h^2+k^2+l^2)

d=5.63/

d=5.63/

d=3.255

B) the scattering angle is calculated by the formula

Scattering angle = n x /pm

61.41°&7.23° will be the scattering angles using the above formula.

C) there will be no change the wavelength of the scattered light because scattering power of the X rays the function of the atomic number.
