John William Strutt, 3rd Baron Rayleigh | Lord Rayleigh's method for the isolation of argon, based on an experiment of Henry Cavendish's.

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.

In the nineteenth century the major figures of mathematical acoustics were Helmholtz in Germany, who consolidated the field of physiological acoustics, and Lord Rayleigh in England, who combined the previous knowledge with his own copious contributions to the field in his monumental work The Theory of Sound ( 1877 ).

Drag theories were developed by Jean le Rond d ' Alembert, Gustav Kirchhoff, and Lord Rayleigh.

Around the year 1900 Lord Rayleigh developed the duplex ( combination of two ) theory of human sound localization using two binaural cues, interaural phase difference ( IPD ) and interaural level difference ( ILD ) ( based on analysis of a spherical head with no external pinnae ).

Lord Rayleigh was elected Fellow of the Royal Society on 12 June 1873, and served as president of the Royal Society from 1905 to 1908.

This type of circularly symmetric optical resonance is called a Whispering Gallery Mode, after Lord Rayleigh coined the term.

A century later, in 1895, Lord Rayleigh discovered that samples of nitrogen from the air were of a different density than nitrogen resulting from chemical reactions.

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 ").

In 1910, Lord Rayleigh discovered that an electrical discharge in nitrogen gas produced " active nitrogen ", an allotrope considered to be monatomic.

Rayleigh scattering, named after the British physicist Lord Rayleigh, is the elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the light.
