In fluid dynamics, Rayleigh's equation or Rayleigh stability equation is a linear ordinary differential equation to study the hydrodynamic stability of a parallel, incompressible and inviscid shear flow. The equation is: $${\displaystyle (U-c)(\varphi ''-k^{2}\varphi )-U''\varphi =0,}$$with See more The equation is named after Lord Rayleigh, who introduced it in 1880. The Orr–Sommerfeld equation – introduced later, for the study of stability of parallel viscous flow – reduces to Rayleigh's equation when the … See more Consider a parallel shear flow $${\displaystyle U(z)}$$ in the $${\displaystyle x}$$ direction, which varies only in the … See more WebSep 18, 2014 · Lord Rayleigh derived the equation for the dynamics of a gas-filled cavity in an incompressible liquid neglecting liquid viscosity, surface tension and thermal effects [].Then this equation was generalized by Plesset [] to include liquid viscosity and surface tension.Now the Rayleigh equation and its generalizations are widely used for studying …

"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. " - Rayleigh's equation
