WebThe acceptance angle is a function of the refractive indices of the core and the cladding materials. The sine of the acceptance angle is called the numerical aperture. Consider the fibre illustrated in Figure 37.1, having a circular core of diameter d, and a uniform refractive index n1, surrounded by a cladding layer of uniform refractive index ... Webcritical angle: [noun] the least angle of incidence at which total reflection takes place.
Webat which point the α-particle would reverse direction, i.e. the scattering angle θwould equal π. On the other hand, if the line of incidence of the α-particle is a distance b, from the nucleus ( bis called the “impact parameter”), then the scattering angle will be smaller. 2.1 Relation between scattering angle and an impact parameter WebThere is a critical angle within which the fault must be cleared if the system is to remain stable and the equal-area criterion is to be satisfied. This angle is known as the critical clearing angle. Consider the system of Fig. 11.9 operating with mechanical input Pi at stady angle δ0. (Pi=Pe) as shown by the point ‘a’ on the power angle ...
