WebIB Physics SL revision - OPTION A (Wave Phenomena) 4 - Rayleigh criteria2. Here is a 3D graphic of two images that are resolved and unresolveddue to diffraction. The onset of diffraction is gradual; prior to limiting resolution, it can still reduce small-scale contrast by causing airy disks to partially overlap. Labs to do. WebWhen two adjacent Airy patterns reach the Rayleigh criterion, the resolution equation reduces to: D = r = 0.61λ/NA. In cases where two adjacent Airy patterns become closer to each other than in the Rayleigh criterion, the separation is known as the Sparrow limit, which is given by the equation: D = 0.47λ/NA
