Rayleigh disk theory
WebThe deflection of the disk is considered positive if the angle between Fig. 2. Variation of angular deflection of the Rayleigh disk with wave-length of the sound. the normal to the disk and the axis of the tube decreases. If the angle increases, the deflection is considered negative. In obtaining this curve, the length of the tube was kept ... WebSelections from Rayleigh’s scientific papers, which are included in the book, are also considered. These selections include papers about the theory of resonance; the intensity and polarization of the scattered light; the manufacture and theory of diffraction-gratings; and the binaural effect.

WebRayleigh disk definition, 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. See more. Far from the aperture, the angle at which the first minimum occurs, measured from the direction of incoming light, is given by the approximate formula: or, for small angles, simply where θ is in radians, λ is the wavelength of the light in meters, and d is the diameter of the aperture in meters. The full width at half maximum is given by .
WebLord Rayleigh, in full John William Strutt, 3rd Baron Rayleigh of Terling Place, (born November 12, 1842, Langford Grove, Maldon, Essex, England—died June 30, 1919, Terling Place, Witham, Essex), English physical scientist who made fundamental discoveries in the fields of acoustics and optics that are basic to the theory of wave propagation in fluids. … WebKonig's theory of the Rayleigh disc assumes the disc to be motionless, apart from its slow rotation. This assumption is unjustifiable in a relatively heavy medium such as water. The …
