Rayleigh Criterion Angle for Circular Aperture Diffraction
The diffraction intensity ratio is the ratio between intensity at a given angle and the incident intensity of light passing through a circular aperture.
The sine of the Rayleigh criterion angle is directly proportional to the wavelength and inversely proportional to aperture radius.
