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 … WebThe torque exerted by heat flow on a disk suspended in liquid helium II has been measured and shown to agree with theoretical values. As reported earlier by P. M. Morse and one of …
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 . Web340 Electromagnetic Field Theory Figure 34.1: The magni cent beauty of nature can be partly explained by Rayleigh scattering [182,183]. When a ray of light impinges on an object, we model the incident light as a plane elec-tromagnetic wave (see Figure 34.2). Without loss of generality, we can assume that the
