I am being introduced to fibre optics in the class and all text books I feffer to derrive Numerical Aperture by applying pythogaras formula on a triangle having refractive indices as it's sides.
NA= √{n1²+n2²} (Square root)
How can the refractive indices be proved to be proportional to the dimentions of the triangle...
Moreover, does the numerical aperture depend on the dimentions of the cable?
