Single ultracold atoms act as slits, stripping away noise and emphasizing the fundamental nature of wave–particle duality ...

The peaks are the fringes generated by interference between light at different frequencies. And just as the fringes in a conventional double-slit experiment become more spread out in space when the ...

Even weirder, when one tries to measure which slit the light is traveling through, the light suddenly behaves as particles and the interference pattern disappears.

Researchers replicated the classic double slit experiment using lasers, but their slits are in time not space.

The film explores the dual nature of light, demonstrating its behavior as both a wave and a particle through an experiment involving a double slit. It shows how light creates an interference ...

Double slit interference. Photons arrive everywhere on the screen, but in the bright/dark regions in a bright/dark quantum state, respectively, that can/cannot excite the atom which is used to ...

The double-slit experiment is of fundamental importance in physics. More than 200 years ago, Thomas Young diffracted light at two adjacent slits, thus generating interference patterns (images ...

In the new experiment, the interference pattern showed up as fringes, or additional peaks in the frequency spectra, which are graphs of the measured light intensity at different frequencies.
