Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.

Light has always carried more than brightness. In this case, it also carries direction and twist. That mix may open a new ...

For a long time, it was thought that this [technique] required telescopes in space,” says John Mather, the Nobel ...

In this video I talk about diffraction gratings and how they work. I show you how you can use them to make diffraction ...

Quantum physics overturned classical ideas by showing that matter behaves very differently at the smallest scales. One of its most surprising discoveries was wave-particle duality, the idea that ...

Scientists have unveiled a new way to capture ultra-sharp optical images without lenses or painstaking alignment. The approach uses multiple sensors to collect raw light patterns independently, then ...

Abstract: The concept of metagratings has been proposed as an efficient method of controlling the diffraction field of electromagnetic waves. In this paper, a reflective metagrating with ...

Article subjects are automatically applied from the ACS Subject Taxonomy and describe the scientific concepts and themes of the article. Since its inception, μLaue diffraction has been primarily used ...

Optical dispersion occurs when the refractive index of a material changes with the wavelength of incoming light. This variation causes different colors to move at different speeds in transparent media ...
