Augustin-Jean Fresnel [Note 1] (10 May 1788 – 14 July 1827) was a French civil engineer and physicist whose research in optics led to the almost unanimous acceptance of the wave theory of light, excluding any remnant of Newton's corpuscular theory, from the late 1830s [3] until the end of the 19th century.
Fresnel, named for the 18th-century physicist Augustin Fresnel, was ordered on 26 August 1905 from the Arsenal de Rochefort. [6] The submarine was laid down in 1906, [7] launched on 16 June 1908 and commissioned on 22 February 1911.
Fresnel was a French Navy Redoutable-class submarine of the M6 series commissioned in 1932. She participated in World War II , first on the side of the Allies from 1939 to June 1940, then in the navy of Vichy France until she was scuttled at Toulon in November 1942.
The Fresnel–Arago laws are three laws which summarise some of the more important properties of interference between light of different states of polarization. Augustin-Jean Fresnel and François Arago , both discovered the laws, which bear their name.
The Huygens–Fresnel principle (named after Dutch physicist Christiaan Huygens and French physicist Augustin-Jean Fresnel) states that every point on a wavefront is itself the source of spherical wavelets, and the secondary wavelets emanating from different points mutually interfere. [1] The sum of these spherical wavelets forms a new wavefront.
The Fresnel Institute was born in 1999, and officially recognized as a French unité mixte de recherche (UMR) on 1 January 2000. [1] The first director was Claude Amra [ d ] . The institute is named after French scientist Augustin-Jean Fresnel , whose research on the wave theory of light led to its near unanimous acceptance.
Augustin Fresnel invented a superior way of focusing light in the early 1850s and most lighthouses in the U.S. was converted to the Fresnel Lens, with Pemaquid Point receiving a fourth order Fresnel in 1856. The lens is one of only six Fresnel lenses still in service in Maine. [4] The keeper's house was built in 1857.
