[struht] /strʌt/ (Show IPA), 3rd Baron, 1842–1919, English physicist: Nobel prize 1904.
Lord, title of John William Strutt, 1842–1919, British physicist. He discovered argon (1894) with Ramsay and made important contributions to the theory of sound, the theory of scattering of radiation, etc. Nobel prize for physics 1904
British physicist whose investigation of the densities of gases led to his discovery (with Sir William Ramsay) of the noble gas argon in 1894. For this work he won the 1904 Nobel Prize for physics.
- Rayleigh disc
noun 1. a small light disc suspended in the path of a sound wave, used to measure the intensity of the sound by analysing the resulting deflection of the disc
noun, Acoustics, Mechanics. 1. a small circular disk, usually of mica, that is suspended from a fiber and tends to be deflected at right angles to a stream of air, indicating by its deflection the intensity of a sound wave.
- Rayleigh distribution
mathematics A curve that yields a good approximation to the actual labour curves on software projects. [Details? Equation?] (1996-05-29)
noun, Optics. 1. the scattering of light by particles that are very small in relation to the wavelength of the light, and in which the intensity of the scattered light varies inversely with the fourth power of the wavelength. noun 1. a process in which electromagnetic radiation is elastically deflected by particles of matter, without […]
