What is the refractive index of fused silica?
Its refractive index varies from 1.55 to 1.40 (for its transparent range: 160nm to 3000nm). Because fused silica is optically stable and consistent, many use it as a reference or standard for spectroscopic measurements. The details of its refractive index temperature dependence are also well studied.
What is the refractive index of fused quartz?
Its quite high Abbe Number of 67.8 makes it among the lowest dispersion glasses at visible wavelengths, as well as having an exceptionally low refractive index in the visible (nd = 1.4585).

What material has the highest index of refraction?
The refractive index rose rapidly for gaps below about 5 µm, and the aluminium material, with its tiny gaps, had the highest maximum index.
Which Colour has the highest refractive index?
The refractive index is maximum for violet colour.
