Abstract (english)
It is shown that the coefficients A_k of angles θ_k, corresponding to the minima of light intensity in the diffraction by a circular aperture, can successfully be described by a function which appears in the electrostatic interaction energy between two uniform surface-charged spheres. The coefficient A_k defines the angle θ_k by sinθ_k = A_kλ/d, k = 1,2,3, ¼ , where λ is the wavelength of light and d is the diameter of the aperture. These coefficients may be correlated with a dimensionless function f_b/R, encountered in the relation of the interaction energy terms of two spheres of equal radii R, with uniformly-distributed surface charges q and q¢ and at a mutual distance b. The total interaction energy, i.e. the Coulomb potential energy, is W = qq¢/(4πε_0b), where ε_0 is the permitivity of vacuum. This energy contains two terms, a positive one W(^+) = W f_b/R and negative one W(^-) = W (1-f_b/R). The correlation between A_k and the function f_b/R is given by A_k - k = u + v f_b/R,k, where u and v are constants. Coefficients A_k obtained by this correlation agree with those defined by the diffraction method within an error of 10^-3% at k = 1, and gradually diminishing to 10^-4% at k = 10.
