Q: What are diffraction gratings? A diffraction grating is an optical component for spectroscopy that splits light into different wavelengths. A typical diffraction grating has thousands of ...

- optical device consisting of a surface with many parallel grooves in it; disperses a beam of light (or other electromagnetic radiation) into its wavelengths to produce its spectrum ...

Scientists have observed “bending” atoms using a crystal grating—an experiment once believed impossible at the high energies ...

Several approaches are capable of beating the classical 'diffraction limit ... localization of light at a distance from the grating, both ideas have the same underlying physics: the tailored ...

Atom diffraction had so far been seen in reflection. The atoms were bounced off a surface that was etched to have a grating. The lines don’t need to be as thin as 10,000 times smaller than a ...

For thousands of years, thinkers argued about whether light is made of particles or waves. At the beginning of the 20th century, scientists realized it was both: massless particles and waves.
