Rayleigh Scattering
Rayleigh scattering ( ) is the scattering or deflection of light, or other electromagnetic radiation, by particles with a size much smaller than the wavelength of the radiation. For light frequencies well below the resonance frequency of the scattering medium (normal dispersion relation, dispersion regime), the amount of scattering is inversely proportional to the fourth power of the wavelength (e.g., a blue color is scattered much more than a red color as light propagates through air). The phenomenon is named after the 19th-century British physicist Lord Rayleigh (John William Strutt). 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 throu ...

Plateau–Rayleigh Instability
In fluid dynamics, 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 total volume but less surface area per droplet. 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#Continuous inkjet, 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-similarity, self-similar solutions. History The Plateau–Rayleigh instability is named for Joseph Plateau and John Strutt, 3rd Baron Rayleigh, Lord Rayleigh. In 187 ...

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 parishes in England, civil parish in the Rochford (district), Rochford District in Essex, England; it is located between Chelmsford, Essex, 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 Rayleig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
