WebJun 1, 2009 · Lord Rayleigh lived across two distinct periods in the history of physics—the classical period, which includes mechanics, thermodynamics, the ether and Maxwell’s equations, and early modern physics, which is based on Einstein’s relativity theory and quantum mechanics. His life overlapped with Roentgen’s discovery of X-rays, Becquerel ... Webdynamic characteristics of the Rayleigh wave were investigated by having the Rayleigh wave interact with different surface geometries. This was accomplished by initiating a forward moving Rayleigh wave on a concave curved surface and on a sharp right-angled surface. The two glass specimens that were used for this process are shown in Figure 7.
