The waves always 'spread' to some extent into the area beyond the gap. This is diffraction - the spreading out of waves when they go through a gap, or past the edge of a barrier. The extent of the ...

IN 1924, Prince Louis de Broglie put forward the thesis that all material particles, and in particular electrons, have properties analogous to those of a train of waves. This view, which is now ...

X-ray diffraction, reflectivity, standing waves and evanescent waves will be discussed in a context that leads to an understanding of how these x-ray methods are presently being used at synchrotrons ...

Here, we are going to talk about the differences between interference and diffraction. Wave Optics of Class 12 Physics covers this topic in detail. Before talking about the concept, let us first ...

The diffraction limit is a fundamental barrier in optical microscopy that sets the minimum size of features that can be resolved using conventional light microscopes. It arises due to the wave nature ...

Students will be able to perform standard x-ray diffraction measurements on metals, ceramics and polymers and quantitatively interpret the results. Students will attain an intermediate level of ...

The goal of the current project is to open a new field of research by realizing the first diffraction experiments of atomic matter waves through crystalline 2D membranes like graphene. Such ...

We have recently succeeded in detecting the diffraction pattern of radio waves scattered from the electron trail as a meteor passes at right angles through the aerial beam. These observations lead ...

Electron diffraction is a powerful analytical technique used to study the atomic structure of materials. It involves the interaction of a beam of electrons with a crystalline sample, resulting in a ...
