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. 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 .

For light frequencies well below the resonance frequency of the scattering particle (normal dispersion regime), the amount of scattering is inversely proportional to the fourth power of the wavelength. fortune house chinese takeaway st austell
