Quotes tagged as "rayleigh" Showing 1-4 of 4. “If a little kid ever asks you just why the sky is blue, you look him or her right in the eye and say, "It's because of quantum effects involving Rayleigh scattering combined with a lack of violet photon receptors in our retinae.”. ― Philip C. Plait, Bad Astronomy.
The Rayleigh number describes the behaviour of fluids (such as water or air) when the mass density of the fluid is non-uniform. The mass density differences are usually caused by temperature differences. Typically a fluid expands and becomes less dense as it is heated. Gravity causes denser parts of the fluid to sink, which is called convection. Lord Rayleigh studied the case of Rayleigh-Bénard convection. When the Rayleigh number, Ra, is below a critical value for a fluid… WebJan 21, 2007 · More precisely, you generate the complex Rayleigh fading weights, at some sampling rate greater than twice the maximum Doppler spread, and compute the log-normal fading independently, and optionally at a much lower sampling rate (linearly interpolate between samples is fine).
