In 1991, Carnal and Mlynek performed the classic Young's double slit experiment with metastable helium atoms passing through micrometer-scale slits in gold foil. [ 64 ] [ 65 ] In 1999, a quantum interference experiment (using a diffraction grating, rather than two slits) was successfully performed with buckyball molecules (each of which ...

Unlike the modern double-slit experiment, Young's experiment reflects sunlight (using a steering mirror) through a small hole, and splits the thin beam in half using a paper card. [6] [8] [9] He also mentions the possibility of passing light through two slits in his description of the experiment: Modern illustration of the double-slit experiment
The electron double slit experiment is a textbook demonstration of wave-particle duality. [2] A modern version of the experiment is shown schematically in the figure below. Left half: schematic setup for electron double-slit experiment with masking; inset micrographs of slits and mask; Right half: results for slit 1, slit 2 and both slits open ...
A wavefront splitting interferometer divides a light wavefront emerging from a point or a narrow slit (i.e. spatially coherent light) and, after allowing the two parts of the wavefront to travel through different paths, allows them to recombine. [13] Fig. 5 illustrates Young's interference experiment and Lloyd's mirror.
In wavefront-division systems, the wave is divided in space—examples are Young's double slit interferometer and Lloyd's mirror. Interference can also be seen in everyday phenomena such as iridescence and structural coloration. For example, the colours seen in a soap bubble arise from interference of light reflecting off the front and back ...
Schematic diagram for the setup of the Young's Double Slit Experiment. In the double slit experiment, originally by Thomas Young in 1801, light from a light source is allowed to pass through two pinholes separated by some distance, and a screen is placed some distance away from the pinholes where the interference between the light waves is ...
In quantum mechanics, a quantum eraser experiment is an interferometer experiment that demonstrates several fundamental aspects of quantum mechanics, including quantum entanglement and complementarity. [1] [2]: 328 The quantum eraser experiment is a variation of Thomas Young's classic double-slit experiment. It establishes that when action is ...
