New audio tech uses ultrasound to create isolated pockets of sound, enabling private listening without headphones.

Researchers have taken atomic diffraction to a new level, revealing surprising behaviors in high-energy helium and hydrogen ...

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 ...

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 ...
