Comprised of unit cells forming a lattice, name these types of solids that consist of a regular pattern of constituent molecules, exemplified by quartz.
Each of these substances has three numbers associated with it, the Miller indices. One law concerning these substances states that twice the distance between their layers times the sine of the angle of incidence of light equals a whole number of wavelengths. Particles within them have associated quantities describing how many nearest neighbors they have, the coordination number; and depending on whether their corners are identical to their centers, these structures can be simple, body-centered, or face-centered. The aforementioned law is named for a father-and- son pair, the Braggs.
