Controlling where sound goes is difficult because of a phenomenon called diffraction – the tendency of sound waves to spread ...

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 ...

Several approaches are capable of beating the classical 'diffraction limit ... where evanescent waves have faded, cannot be far from that given by the well-known Abbe–Rayleigh rule, according ...

Conventional curved lenses, which direct light by refraction in glass or plastic, are often bulky and heavy, offering only ...

The film explains the concept of electromagnetic waves, particularly focusing on their applications in radar, radio, and television. It describes how a crystal set functions as a simple radio receiver ...

Description: Electron diffraction patterns for single crystal and polycrystalline materials are displayed on a CRT screen. A Welch model 2639 'Electron Diffraction tube' is used in an experiment in ...

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 ...
