WebIn physics and electrical engineering the reflection coefficient is a parameter that describes how much of a wave is reflected by an impedance discontinuity in the transmission medium. It is equal to the ratio of the amplitude of the reflected wave to the incident wave, with each expressed as phasors.For example, it is used in optics to calculate the amount of light … WebThe Rayleigh number is proportional to the coefficient of thermal expansion, so at some point the Rayleigh number must pass through the critical Rayleigh numbers found here.

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.
