Question Description
Light guidance in an optical fibre can be understood by considering a structure comprising of thin solid glass cylinder of refractive index n1 surrounded by a medium of lower refractive index n2.The light guidance in the structure takes place due to successive total internal reflections at the interface of the media n1 and n2 as shown in the figure. All rays with the angle of incidence i less than a particular value im are confined in the medium of refractive index n1. The numerical aperture (NA) of the structure is defined as sin im.Q.For two structure namely S1 withand n2 = 3/2, and S2 with n1 = 8/5 and n2 = 7/5 and taking the refractive index of water to be 4/3 and that of air to be 1, the correct option(s) is(are)a)NA of S1 immersed in water is the same as that of S2 immersed in a liquid of refractive indexb)NA of S1 immersed in liquid of refractive indexis the same as that of S2 immersed in waterc)NA of S1 placed in air is the same as that of S2 immersed in liquid of refractive indexd)NA of S1 placed in air is the same as that of S2 placed in waterCorrect answer is option 'A,C'.
