Experimentally, the Bragg law can be applied in two different ways:

Experimentally, the Bragg law can be applied in two different ways: By using x-rays of known ? and measuring the angle ? we can determine the spacing d of various planes in a crystal: this is called structure analysis (X-ray diffraction or XRD)

X-Ray Diffraction

X-Ray Diffraction

X-Ray Diffraction. The XRD Technique. Takes a sample of the material and places a powdered sample which is then illuminated with x-rays of a fixed wave-length. The intensity of the reflected radiation is recorded using a goniometer.
