An illustration of the Double Slit Experiment: light from one slit interferes with light from the other, producing an interference pattern (the 3 fringes shown at the right). In modern physics, the double-slit experiment demonstrates that light and matter can exhibit behavior of both classical particles and classical waves.
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
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 ...

Thomas Young published his double-slit experiment in 1807. [9] The original Arago spot experiment was carried out a decade later and was the deciding experiment on the question of whether light is a particle or a wave. It is thus an example of an experimentum crucis.
[2]: 184 Like the double-slit experiment, Wheeler's concept has two equivalent paths between a source and detector. Like the which-way versions of the double-slit, the experiment is run in two versions: one designed to detect wave interference and one designed to detect particles. The new ingredient in Wheeler's approach is a delayed-choice ...
The N-slit interferometer is an extension of the double-slit interferometer also known as Young's double-slit interferometer. One of the first known uses of N-slit arrays in optics was illustrated by Newton. [1] In the first part of the twentieth century, Michelson [2] described various cases of N-slit diffraction.
