Rayleigh Scattering
Rayleigh scattering ( ), named after the 19th-century British physicist Lord Rayleigh (John William Strutt), is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. For light frequencies well below the resonance frequency of the scattering particle (normal dispersion regime), the amount of scattering is inversely proportional to the fourth power of the wavelength. Rayleigh scattering results from the electric polarizability of the particles. The oscillating electric field of a light wave acts on the charges within a particle, causing them to move at the same frequency. The particle, therefore, becomes a small radiating dipole whose radiation we see as scattered light. The particles may be individual atoms or molecules; it can occur when light travels through transparent solids and liquids, but is most prominently seen in gases. Rayleigh scattering of sunlight in Earth's atmosphere causes d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plateau–Rayleigh Instability
The Plateau–Rayleigh instability, often just called the Rayleigh instability, explains why and how a falling stream of fluid breaks up into smaller packets with the same volume but less surface area. It is related to the Rayleigh–Taylor instability and is part of a greater branch of fluid dynamics concerned with fluid thread breakup. This fluid instability is exploited in the design of a particular type of ink jet technology whereby a jet of liquid is perturbed into a steady stream of droplets. The driving force of the Plateau–Rayleigh instability is that liquids, by virtue of their surface tensions, tend to minimize their surface area. A considerable amount of work has been done recently on the final pinching profile by attacking it with self-similar solutions. History The Plateau–Rayleigh instability is named for Joseph Plateau and Lord Rayleigh. In 1873, Plateau found experimentally that a vertically falling stream of water will break up into drops if its length ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rayleigh (lunar Crater)
Rayleigh is a lunar impact crater, approximately 114 kilometers in diameter, that lies along the northeast limb of the Moon. This feature is seen edge-on from Earth, making it difficult to see much detail. In addition, libration effects can completely hide this crater from view. It lies just to the north of Lyapunov, and to the northwest of the large Joliot. Attached to its southwest rim is the smaller Urey. Description This is an eroded formation with a rim that has been worn and reshaped by impacts. This is particularly so in the south where the rim has been modified and supplemented by adjacent crater formations and several small craters that lie along the rim. The interior floor is relatively level in places, but, partly due to overlapping ejecta, is somewhat rough and irregular in others, particularly in the southern half. A pair of small but prominent craters lies on the interior surface, with Rayleigh D just to the south of the crater midpoint and the smaller Ra ...

Rayleigh, Essex
Rayleigh is a market town and civil parish in Essex, England; it is located between Chelmsford and Southend-on-Sea, east of central London. It had a population of 32,150 at the census in 2011. Toponymy The name ''Rayleigh'' is Old English in origin deriving from ''rǣge'' ('female roe-deer or she-goat') and ''lēah'' ('clearing'). Therefore, the name means overall 'wood or clearing of the wild she-goats or roe-deer". History Prehistoric and Roman times There has been a scattering of stray finds around the town from Prehistoric and Roman times, including some Roman roof and hypocaust tiles found within the fabric of Rayleigh Church. This suggests that there was a Roman habitation site within the area. However, there is little evidence of any density of population here during this period. Saxon era One significant archaeological find was in the early 2000s at the western edge of Rayleigh, at the site of the former Park School in Rawreth Lane. An early Saxon cemetery site was d ...

Rayleigh, British Columbia
Rayleigh is a neighbourhood of Kamloops, British Columbia, Canada along Highway 5 (the Yellowhead Highway). It is located on the east side of the North Thompson River The North Thompson River is the northern branch of the Thompson River, the largest tributary of the Fraser River, in the Canadian province of British Columbia. It originates at the toe of the Thompson Glacier in the Premier Range of the Cariboo ... and south of the community of Heffley Creek. History In May 1973, the municipality of Rayleigh was added to the city of Kamloops. A former post office here was named Rayleigh Mount. This post office was named by the first postmaster W A Belcham after his home town in England. He, his wife Elizabeth, and son W A K Belcham operated the post office until the 1940s when they moved to Little Fort. Native reserve lands and the Thompson River separate Rayleigh and Heffley Creek from the rest of Kamloops. In the past years the City of Kamloops finished building a new ...

Robert John Strutt, 4th Baron Rayleigh
Robert John Strutt, 4th Baron Rayleigh (28 August 1875 – 13 December 1947) was a British peer and physicist. He discovered "active nitrogen" and was the first to distinguish the glow of the night sky. Early life and education Strutt was born at Terling Place, the family home near Witham, Essex, the eldest son of John William Strutt, 3rd Baron Rayleigh and his wife Evelyn Georgiana Mary (). He was thus a nephew of Arthur Balfour and of Eleanor Mildred Sidgwick. He was educated at Eton College and Trinity College, Cambridge, where he initially read mathematics, but changed after two terms to Natural Sciences.A. C. Egerton, 'Strutt, Robert John, fourth Baron Rayleigh (1875–1947)', rev. Isobel Falconer He became a research student in physics at the Cavendish Laboratory under J. J. Thomson, whose biography he subsequently wrote. His work at this time was on discharge of electricity through gases, including early work on x-rays and electrons.

John William Strutt, 3rd Baron Rayleigh
John William Strutt, 3rd Baron Rayleigh, (; 12 November 1842 – 30 June 1919) was an English mathematician and physicist who made extensive contributions to science. He spent all of his academic career at the University of Cambridge. Among many honors, he received the 1904 Nobel Prize in Physics "for his investigations of the densities of the most important gases and for his discovery of argon in connection with these studies." He served as president of the Royal Society from 1905 to 1908 and as chancellor of the University of Cambridge from 1908 to 1919. Rayleigh provided the first theoretical treatment of the elastic scattering of light by particles much smaller than the light's wavelength, a phenomenon now known as "Rayleigh scattering", which notably explains why the sky is blue. He studied and described transverse surface waves in solids, now known as "Rayleigh waves". He contributed extensively to fluid dynamics, with concepts such as the Rayleigh number (a dimensio ...

Charlotte Mary Gertrude Strutt, 1st Baroness Rayleigh
Charlotte Mary Gertrude Strutt, 1st Baroness Rayleigh (29 May 1758 – 13 September 1836), known as Lady Charlotte FitzGerald from 1758 to 1789 and as Lady Charlotte Strutt from 1789 to 1821, was a British peeress. Charlotte was the daughter of James FitzGerald, 1st Duke of Leinster, and his wife, Lady Emily, daughter of Charles Lennox, 2nd Duke of Richmond, and the second of the famous Lennox sisters. Lord Edward FitzGerald and Charles FitzGerald, 1st Baron Lecale, were her brothers. Through her mother she was a descendant of King Charles II. In Toulouse on 23 February 1789 Charlotte married Joseph Strutt, later Member of Parliament for Maldon and the member of an Essex family that had made their fortune from its milling business. The couple had three children: a son, John (later the second Baron Rayleigh), and two daughters. Her husband was offered a peerage for his services in the Army and Parliament but refused, and instead proposed that the honour be given to his wife. ...

Baron Rayleigh
Baron Rayleigh, of Terling Place in the County of Essex is a title in the Peerage of the United Kingdom. The peerage was created on 18 July 1821 for Lady Charlotte Strutt, wife of Colonel Joseph Strutt, Member of Parliament for Maldon. Strutt had earlier declined the offer of a peerage, 'under a cloak of false humility' and instead proposed that the honour be given to his wife. Lady Rayleigh was the daughter of James FitzGerald, 1st Duke of Leinster, and his wife Lady Emily Lennox, the second of the famous Lennox sisters. Her elder brother was Charles FitzGerald, 1st Baron Lecale, and her younger brother was Lord Edward FitzGerald. The family seat is Terling Place, Essex. The title is currently held by the fourth Baron's grandson, the sixth Baron, who succeeded his uncle in 1988.

Rayleigh–Taylor Instability
The Rayleigh–Taylor instability, or RT instability (after Lord Rayleigh and G. I. Taylor), is an instability of an interface between two fluids of different densities which occurs when the lighter fluid is pushing the heavier fluid. Drazin (2002) pp. 50–51. Examples include the behavior of water suspended above oil in the gravity of Earth, mushroom clouds like those from volcanic eruptions and atmospheric nuclear explosions, supernova explosions in which expanding core gas is accelerated into denser shell gas, instabilities in plasma fusion reactors and inertial confinement fusion. Water suspended atop oil is an everyday example of Rayleigh–Taylor instability, and it may be modeled by two completely plane-parallel layers of immiscible fluid, the denser fluid on top of the less dense one and both subject to the Earth's gravity. The equilibrium here is unstable to any perturbations or disturbances of the interface: if a parcel of heavier fluid is displaced downward with a ...

Rayleigh–Ritz Method
The Rayleigh–Ritz method is a direct numerical method of approximating eigenvalues, originated in the context of solving physical boundary value problems and named after Lord Rayleigh and Walther Ritz. The name Rayleigh–Ritz is being debated vs. the Ritz method after Walther Ritz, since the numerical procedure has been published by Walther Ritz in 1908-1909. According to, Lord Rayleigh wrote a paper congratulating Ritz on his work in 1911, but stating that he himself had used Ritz's method in many places in his book and in another publication. This statement, although later disputed, and the fact that the method in the trivial case of a single vector results in the Rayleigh quotient make the arguable misnomer persist. According to, citing Richard Courant, both Lord Rayleigh and Walther Ritz independently conceived the idea of utilizing the equivalence between boundary value problems of partial differential equations on the one hand and problems of the calculus of variations on t ...
