Rayleigh criterion wiki
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 . WebRayleigh scattering, dispersion of electromagnetic radiation by particles that have a radius less than approximately 110 the wavelength of the radiation. The process has been named in honour of Lord Rayleigh, who in 1871 …
