Find the interplanar spacing between consecutive (101) planes in an orthorhombic crystal with lattice parameters a=252A°, b=1.72 A°, and c = 2.84A°.

We wish to analyze the interplanar spacing of NaF. We perform an X-ray diffraction experiment with 0.140 nm X-rays. We measure the angle of the first order maximum; it is 17.72°. Calculate the interplanar spacing in the NaF crystal.

X-rays of wavelength 0.140 nm are reflected from a certain crystal, and the first-order maximum occurs at an angle of 14.4°. What value does this give for the interplanar spacing of the crystal?

An x-ray beam of wavelength A undergoes first-order reflection froma crystal when its angle of incidence to a crystal face is 27 °,and an x-ray beam of wavelength 96 pm undergoes third-orderreflection when its angle of incidence to that face is 60°.Assuming that the two beams reflect from the same family ofreflecting planes, find (a) the interplanar spacing and (b) thewavelength A.
