WebThe pressure is given by the condition of hydrostatic equilibrium, that is P = P 0 - 0.1ρy, where P 0 =2.5, and γ = 1.4. This gives a sound speed of 3.5 in the low density medium at the interface. The structures which appear in the nonlinear regime are very sensitive to the nature of the perturbations used to seed the intability. WebThe Rayleigh condition was confirmed with a spectrometer. A GretagMacbeth Color Checker test chart was set up near normal illumination to sunlight (Figure 3). A steerable mirror was set up to reflect the Rayleigh-blue sky into the same field of view as the color chart. The mirror was in shade to avoid scattering of sunlight off the mirror.
