X-rays with wavelengths of 128 pm was used to study a crystal which produced a reflection of 15.8 degrees. Assuming first order diffraction (n = 1), what is the distance between the planes of atoms (d)
When a crystal absorbs a photon, that energy becomes part of the crystal. When that same crystal releases a photon, that photon is taking energy away from the crystal. The Stokes Shift is a measure of the difference in wavelength (and thus energy) of photons absorbed by a crystal and then immediately re-emitted by that same crystal. The energy shift between the two photons is an indication of how much energy has been permanently absorbed by the crystal in the form of heat.
you have to measure the distance and angles between the main point and the surrounding pattern from the diffraction you create. Each crystal has its own structure (BCC, FCC, HCP, etc...) and each element in the crystal structure determines the lattice spacing....
look in textbook
there are air spaces

Send a beam of electrons through a crystal structure. If DeBroglie is correct, then the scattering of these electrons will exhibit interference patterns, with wavelengths equal to the DeBroglie Wavelength. If he is wrong, no such interference pattern will be seen. Such interference patterns have been unambiguously seen for decades, starting in 1927.

Crystal Radii is also known as "Metallic Radii ". It is defined as "half the distance between the nuclei of two adjacent metal atoms in the metallic closed packed crystal lattice". It is used for metal atoms which are assumed to be closely packed spheres in the metallic crystal. As for ionic radii .... I don't know.
what is the difference between an cubic and a tetragonal crystal
It means "between planes". Usually this is interplanar distace which is the distance between planes of atoms or molecules in a crystal lattice. Any one define the above with diagram?
The shortest driving distance is 47.7 miles.
