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

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 ...

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 ...

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 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 ...

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 ...

Audible enclaves are small pockets of sound that are not disturbed by surrounding noise. They are produced by new ...

Definition: X-Ray Diffraction (XRD) is a powerful analytical technique used to characterize the atomic and molecular structure of a crystal. By measuring the angles and intensities of diffracted beams ...
