Braggs law nl 2d sinq

• explain why the planes of atoms in crystals
  appear to reflect X-ray beams at certain angles
  of incidence (theta, q)
• the order of the reflection (n)
• the wavelength (l)
• spacing of the multilayer which is equal to the
  sum of the thickness of one layer pair of the
  high-Z and low-Z materials (d)
• the incident angle between the x-ray beam and the
  plane of the multilayer (2q)
