Episode 529: Preparation for X- ray and neutron diffraction topic

 

 

Students can apply their understanding of diffraction to X-ray and neutron diffraction studies of the structure of matter.

This topic could extend a study of diffraction of waves, or be part of a study of material structures, or of atomic physics.

 

Episode 530: X-ray diffraction

Episode 531: Neutron diffraction

 

Main aims

Students will:

  1. Relate diffraction effects to the spacing of gratings etc. and to the wavelength of the radiation involved.
  2. State some uses of X-ray and neutron diffraction.
  3. Apply Bragg’s law.
 
Diffraction of a plane wave by a grating

 

Prior knowledge

Students should be familiar with diffraction due to a standard (transmission) grating (d sin q = nl), de Broglie’s formula l = h/p. It will also help if they are aware that, at (absolute) temperature T, typical energy ~ kT.

 

Where this leads

This topic could lead into a study of the structures and properties of solid materials.
