Problem

The Malitson Sellmeier equation for fused silica is

n^2(\lambda) = 1 + \frac{0.6961663\,\lambda^2}{\lambda^2 - 0.0684043^2} + \frac{0.4079426\,\lambda^2}{\lambda^2 - 0.1162414^2} + \frac{0.8974794\,\lambda^2}{\lambda^2 - 9.896161^2},

with

\lambda

in micrometres. Use this to find the refractive index of fused silica at a vacuum wavelength of

1.000\ \mu\mathrm{m}
