Rayleigh and Ramsay received the 1904 Nobel Prizes in Physics and in Chemistry, respectively, for their discovery of the noble gases ; in the words of J. E. Cederblom, then president of the Royal Swedish Academy of Sciences, " the discovery of an entirely new group of elements, of which no single representative had been known with any certainty, is something utterly unique in the history of chemistry, being intrinsically an advance in science of peculiar significance ".

Rayleigh and Ramsay
Argon ( αργος, Greek meaning " inactive ", in reference to its chemical inactivity ) was suspected to be present in air by Henry Cavendish in 1785 but was not isolated until 1894 by Lord Rayleigh and Sir William Ramsay in Scotland in an experiment in which they removed all of the oxygen, carbon dioxide, water and nitrogen from a sample of clean air.
John William Strutt, 3rd Baron Rayleigh, OM ( 12 November 1842 – 30 June 1919 ) was an English physicist who, with William Ramsay, discovered argon, an achievement for which he earned the Nobel Prize for Physics in 1904.
Along with scientist William Ramsay at University College, London, Lord Rayleigh theorized that the nitrogen extracted from air was mixed with another gas, leading to an experiment that successfully isolated a new element, argon, from the Greek word (, " inactive ").

Geophysical techniques used for subsurface exploration include measurement of seismic waves ( pressure, shear, and Rayleigh waves ), surface-wave methods and / or downhole methods, and electromagnetic surveys ( magnetometer, resistivity, and ground-penetrating radar ).
Rayleigh scattering of sunlight in the atmosphere causes diffuse sky radiation, which is the reason for the blue color of the sky and the yellow tone of the sun itself.
The amount of Rayleigh scattering that occurs for a beam of light depends upon the size of the particles and the wavelength of the light.
The Rayleigh scattering coefficient for a group of scattering particles is the number of particles per unit volume N times the cross-section.
In this case, the Rayleigh scattering intensity for a single particle is given by
Rayleigh scattering is a good approximation of the manner in which light scattering occurs within various media for which scattering particles have a small size parameter.

Typically, for free convection, the average Nusselt number is expressed as a function of the Rayleigh number and the Prandtl number, written as: Nu = f ( Ra, Pr ).
In fluid mechanics, the Rayleigh number for a fluid is a dimensionless number associated with buoyancy driven flow ( also known as free convection or natural convection ).
When the Rayleigh number is below the critical value for that fluid, heat transfer is primarily in the form of conduction ; when it exceeds the critical value, heat transfer is primarily in the form of convection.

Rayleigh fading is viewed as a reasonable model for tropospheric and ionospheric signal propagation as well as the effect of heavily built-up urban environments on radio signals.
In his book, Jakes popularised a model for Rayleigh fading based on summing sinusoids.
