Even younger: illustration of the new double-slit experiment using resonant inelastic X-ray scattering on an iridium oxide crystal. An intense beam of high-energy X-ray photons (violet) hits two ...

According to quantum mechanics, the motion of massive particles is described by wave theory. This wave nature of matter is most strikingly demonstrated by observing an interference pattern in the ...

This article is an extended version of the article “The double-slit experiment” that appeared in the September 2002 issue of Physics World (p15). It has been further extended to include three letters ...
