The refractive index of fused silicais given, as a function of wavelength l, in µm, by
Use this expression to calculate therefractive index of fused silica at a wavelength of 1.59µm andcomment on the relative importance of the contributions from eachof the three different terms in the expression. Sketch therefractive index versus wavelength curve over the range 0.3 µm to3.5 µm and discuss the wavelength range in which the expression isvalid.
