WebJan 19, 2024 · The Rayleigh Criterion is a slightly refined formula based on Abbe’s diffraction limits: R = 1.22λ/(NA obj + NA cond) where λ is the wavelength of light used to image a specimen. NA obj is the NA of the objective. NAcond is the NA of the condenser. The value ‘1.22’ is a constant. This is derived from Rayleigh’s work on Bessel Functions. WebJan 17, 2024 · As it is inversely proportional to kinematic viscosity so the higher it's value Rayleigh number get lowered and steady roll of fluid can't be observed. Thats right. In nat convection problems, as fluid velocity is unknown, Ra is used to determine the flow regime. If Ra <<< 10^7, the fluid flow is laminar, HT dominated by conduction.
