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 ...

Abstract: Recently, the studies about the vector optical field have attracted a lot of interest due to its novel properties and potential applications. Compared to a scalar optical field with the ...

Three's company: interference patterns for one to four slits (expand for full image) A group of physicists in Austria has directed a beam of large molecules at a series of extremely narrow slits to ...

Thomas Young, born 250 years ago this week, was a polymath who made seminal contributions in fields from physics to Egyptology. But perhaps his most enduring legacy is proving Isaac Newton wrong about ...

The simulation visualizes the intensity distribution of light on a distant screen after passing through one or two narrow slits. This is primarily based on Huygens' principle and the principle of ...

The ability to detect single photons (the smallest energy packets constituting electromagnetic radiation) in the infrared range has become a pressing need across numerous fields, from medical imaging ...

The word uncertainty is used a lot in quantum mechanics. One school of thought is that this means there’s something out there in the world that we are uncertain about. But most physicists believe ...

Bohm’s variation of the Einstein-Podolsky-Rosen thought experiment may reveal the path a photon travels in Young’s experiment without causing the interference pattern to disappear. Unlike in Young’s ...
