The lattice spacing a between the vertical columns of atoms in the figure.

Question

A simple cubic crystal is cut so that the rows of atoms on its surface are separated by a distance of 0.352 nm. A beam of electrons is accelerated through a potential difference of 175 V and is incident on the surface. If all diffraction orders are possible, at what angles, relative to the crystal surface, would the diffracted beams be observed? me = 9.11 x 10-31 kg. 5.

X rays with a wavelength of 0.105 nm are diffracted by a crystal with a simple cubic lattice. Diffraction maxima are observed at angles 31.6° and 55.4° and at no angles between these two. What is the spacing between the atomic planes that cause this diffraction?
