WebThe inversion of Rayleigh surface waves provided a subsurface estimate for the uppermost 8 m of the lunar subsurface with the shear wave velocities varying from 40 to 50 m/s at the surface to velocities in the range of 95–145 m/s with an average of 120 m/s at … WebSep 24, 2024 · The Rayleigh criterion is therefore not a fundamental physical law and instead a somewhat arbitrarily defined value. This was clearly stated by Rayleigh himself in 1879: 2 This rule is convenient on account of its simplicity; and it is sufficiently accurate in view of the necessary uncertainty as to what exactly is meant by resolution.
