Using X-ray DiffractionWhen an x-ray beam is scattered off the planes of a crystal, the scatteredbeam creates an interference pattern. This phenomenon is called Braggscattering. For an observer to measure an interference maximum, twoconditions have to be satisfied:1. The angle of incidence has to be equal to the angle ofreflection.2. The difference in the beam's path from a source to anobserver for neighboring planes has to be equal to an integermultiple of the wavelength; that is,2d sin(0) = mxfor m = 1, 2, ....The path difference 2d sin(0) can be determined from the diagram (Figure 1).

Electromagnetic Plane Waves: In infrared optical systems germanium is often used to form optical components. For infrared wavelengths, germanium can be considered lossless, non-magnetic (u- 1) and has a relative dielectric constant e 16. Consider a plane wave inside a piece of germanium incident at the interface between germanium and air. The plane wave is polarized parallel to the plane of incidence and the angle of incidence is halfway between the Brewster angle and the critical angle for total internal reflection.
