Derive the expression for critical angle

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.
