A dimensionless number named after this man indicates whether or not convection will occur. A scattering named after this man does not change the wavelength of light. The quantity 1.22 times the wavelength over the aperture diameter, a (*) "criterion" for the resolution of two images, is named after this man. Along with Jeans, this man names an equation for blackbody radiation that applies only at long wavelengths.
