WebApr 12, 2024 · The influence of the semi-vertex angle of the conical shell on the critical free-stream static pressure is given in Figure 10. It can be observed that with the increase in the semi-vertex angle, the critical free-stream static pressure decreases accordingly. Furthermore, the natural frequency is inversely proportional to the semi-vertex angle. WebThe accepted criterion for determining the diffraction limit to resolution based on this angle was developed by Lord Rayleigh in the 19th century. The Rayleigh criterion for the …

Webused, the Rayleigh wave energy must have propagated through the array and in a direction parallel to the axis of the array. Rayleigh wave energy that propagates parallel to the axis of a linear array will exhibit lower apparent velocities (greater slowness) than energy that propagates through the same array at an angle. http://plaza.ufl.edu/dwhahn/Rayleigh%20and%20Mie%20Light%20Scattering.pdf
