Interference

Jonathan Allday

Science, as it is generally described at school, starts with experimental data. Scientists then have to find some hypothesis which explains these results. Using this hypothesis, a prediction is made about what might happen in a slightly different experiment. The double-slit experiment is a modified version of the setup first used by Thomas Young in 1801. Young’s version is a classic experiment that, at the time, seemed to have settled the dispute between wave and particle views of light decisively in favour of waves. The idea that particles might display some wavelike properties dates to the mid-1920s when a young PhD student called Louis De Broglie was thinking about the dual wave/particle nature of light. A quantum mechanical description of the double-slit experiment must involve a set of amplitudes governing the passage of an electron through the slits to the far detector.Science, as it is generally described at school, starts with experimental data.

A Possible Resolution of the Enigmatic Double Slit Experiment

Shlomo Barak

We dispel the need to attribute a dualistic nature to single photons that arrive, in a double slit experiment, at the screen one at a time. Interference is explained in a novel way based on known and accepted physics. The photon, being an excitation of the electromagnetic field, is regarded as kind of a “particle”, not yet modeled, of a defined size, and not a wave.

Young’s double-slits goes temporal

Edwin Cartlidge

A “time” version of the famous experiment generates fringes in frequency rather than space, as Edwin Cartlidge explains.

Strange patterns of light

Tao Tang

In a modern version of Young's double slit experiment, a laser beam passes through two narrow slits and creates an interference pattern of bright and dark fringes on a distant screen. We place magnifying glasses between the double-slit and the screen, and when a laser beam passes through the double-slit and magnifying glasses, strange patterns will appear on the screen.
