WebThe angular separation between two objects must be. Θ = 1.22 λ D. Resolving power is defined as the inverse of the distance or angular separation between two objects which can be resolved through the optical instrument. Therefore, R e s o l v i n g P o w e r = 1 Δ Θ = d 1.22 λ. Thus, the higher the diameter d, the better the resolution. In probability theory and statistics, the Rayleigh distribution is a continuous probability distribution for nonnegative-valued random variables. Up to rescaling, it coincides with the chi distribution with two degrees of freedom. The distribution is named after Lord Rayleigh .
