Episode 529: Preparation for X-ray and neutron diffraction topic
Teaching Guidance for 16-19
- Level Advanced
This topic could extend a study of diffraction of waves, or be part of a study of material structures, or of atomic physics.
Main aims of this topic
- relate diffraction effects to the spacing of gratings etc and to the wavelength of the radiation involved
- state some uses of X-ray and neutron diffraction
- apply Bragg’s law
Students should be familiar with diffraction due to a standard (transmission) grating dsin( θ ) = n × λ , de Broglie’s formula λ = hp. 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.
