The double-slit experiment can illustrate the path integral formulation of quantum mechanics provided by Feynman. [82] The path integral formulation replaces the classical notion of a single, unique trajectory for a system, with a sum over all possible trajectories. The trajectories are added together by using functional integration.
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] [10] [11] He also mentions the possibility of passing light through two slits in his description of the experiment: Modern illustration of the double-slit experiment
With Young's interference experiment, the predecessor of the double-slit experiment, he demonstrated interference in the context of light as a wave. Plate from "Lectures" of 1802 (RI), pub. 1807. Young, speaking on 24 November 1803, to the Royal Society of London, began his now-classic description of the historic experiment: [35]
1801 – Thomas Young: double-slit experiment demonstrates the wave nature of light. 1820 – Hans Christian Ørsted discovers the connection between electricity and magnetism. 1843 – James Prescott Joule measures the equivalence between mechanical work and heat, resulting in the law of conservation of energy.
Cavendish experiment (1798): Henry Cavendish's torsion bar experiment measures the force of gravity in a laboratory. Double-slit experiment (c.1805): Thomas Young shows that light is a wave in his double-slit experiment.
Double-slit experiment supports the wave theory of light and demonstrates the effect of interference. 1806: Alessandro Volta: Employing a voltaic pile of approximately 250 cells, or couples, decomposed potash and soda, showing that these substances were respectively the oxides of potassium and sodium, which metals previously had been unknown.
Isaac Newton was born (according to the Julian calendar in use in England at the time) on Christmas Day, 25 December 1642 (NS 4 January 1643 [a]) at Woolsthorpe Manor in Woolsthorpe-by-Colsterworth, a hamlet in the county of Lincolnshire. [27] His father, also named Isaac Newton, had died three months before.
From the modern perspective, the result of Young's double slit experiment (see Fig. 2) clearly points towards the wave nature of light, but such was not the case in the early 1800s. Newton, after all, had observed what are now recognized as diffraction phenomena, and wrote on them in his Third Book of Optics, [ 22 ] interpreting them in terms ...
