Answer to Question #60471 in Optics for Amit Sharma
Question #60471
Define numerical aperture and angle of acceptance. An optical fiber has a numerical
aperture of 0.20 and cladding refractive index of 1.59. Calculate the refractive index
of the core material and the acceptance angle of the fibre in water whose refractive
index is 1.33.
