Thomas Young's sketch of interference based on observations of water waves [6] In 1801, Young presented a famous paper to the Royal Society entitled "On the Theory of Light and Colours" [7] which describes various interference phenomena. In 1803, he described his famous interference experiment. [8]
In Young's own judgment, of his many achievements the most important was to establish the wave theory of light set out by Christiaan Huygens in his Treatise on Light (1690). [ 33 ] [ 34 ] To do so, he had to overcome the century-old view, expressed in the venerable Newton's Opticks , that light is a particle.
[3] [4] [5] Thomas Young's experiment with light was part of classical physics long before the development of quantum mechanics and the concept of wave–particle duality. He believed it demonstrated that the Christiaan Huygens' wave theory of light was correct, and his experiment is sometimes referred to as Young's experiment [6] or Young's ...
However by the turn of the century, beginning with Thomas Young's double-slit experiment in 1801, more evidence in the form of novel experiments on diffraction, interference, and polarization showcased issues with the theory. A wave theory based on Young, Augustin-Jean Fresnel and François Arago's work would materialise in a novel wave theory ...
At the beginning of the 19th century, the idea that light does not simply propagate along straight lines gained traction. 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.
Huygens' theory served as a fundamental explanation of the wave nature of light interference and was further developed by Fresnel and Young but did not fully resolve all observations such as the low-intensity double-slit experiment first performed by G. I. Taylor in 1909.
Christiaan Huygens Thomas Young's sketch of a double-slit experiment showing diffraction. Young's experiments supported the theory that light consists of waves. The wave theory predicted that light waves could interfere with each other like sound waves (as noted around 1800 by Thomas Young).
Thomas Young and Hermann von Helmholtz assumed that the eye's retina consists of three different kinds of light receptors for red, green and blue.. The Young–Helmholtz theory (based on the work of Thomas Young and Hermann von Helmholtz in the 19th century), also known as the trichromatic theory, is a theory of trichromatic color vision – the manner in which the visual system gives rise to ...
