Where the article explains it
where is the known X-ray wavelength, d is the spacing between a family of lattice planes, and is half the scattering angle at which a peak appears.
The passage around this formula
where is the known X-ray wavelength, d is the spacing between a family of lattice planes, and is half the scattering angle at which a peak appears. Peak positions alone give the lattice parameters; peak intensities and shapes carry the rest of the story, and that is where the real work is.
Learn the underlying idea
A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
