Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.

Distinguished for his pioneering studies in X-ray diffraction physics, especially for his development of the technique of X-ray topography, Andrew Lang will be greatly missed by many researchers for ...

The double-slit experiment, first performed by [Thomas Young] in 1801 provided the first definitive proof of the dual wave-particle nature of photons. A similar experiment can be performed that shows ...

Although electron backscatter diffraction (EBSD) was first discovered by Kikuchi in 1928, its potential for microstructural characterization became fully realized only after the technique was ...

This page contains hints, solutions, and advanced challenges for our diffraction grating challenge. If you would like a grating (or a set for your class if you are a teacher), please contact us at ...

Andrew Lang, Emeritus Professor of Physics at the University of Bristol, died in June. He joined the University in 1960 and was promoted to Professor of Physics in 1979. Andrew Lang, Emeritus ...
