The emergence of imaging schemes capable of overcoming Abbe's diffraction barrier is revolutionizing optical microscopy. In 1873, the German physicist Ernst Abbe realized that the resolution of ...

To explain it simple manner, diffraction is the phenomenon that takes place on the bending of light rays at the edge of the obstacle. Due to diffraction, a single slit is formed which creates a ...

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 ...

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 ...
