Class Practical: A diffraction pattern showing bands of colour produced from white light.
Class practical: A group of short, introductory experiments to investigate the behaviour of concave and convex lenses using...
Demonstration: Refraction at an air-water interface and total internal reflection.
Demonstration: This ripple tank experiment models the action of a diffraction grating.
The diffraction grating was named by Fraunhofer in 1821, but was in use before 1800. There is a good case for describing it is...
