Episode 530: X- ray Diffraction
This learning episode, from the Institute of Physics, uses laser light to demonstrate the phenomenon of diffraction and then applies this understanding to x-rays, Bragg's law and crystallography.
The activities in this episode look at:
• students’ knowledge of X-rays
• diffraction and the limits of resolution
• diffraction of laser light and crystal models
• deriving Bragg’s law
• demonstration of crystal spacing by X-rays
• analogues of X-ray diffraction
• chemical composition by X-ray analysis
