A diamond has the highest index of refraction, about 2.4 Crown glass is about 1.5 and a vacuum is 1
The velocity of light travelling through a material relates to the index of refraction of that material. In this group, air has the lowest index of refraction, follow by water, fused quartz, and crown glass. This means like travels the fastest through air, then water, then fused quarts, and finally glass.
The answer would be air. The other mediums have higher indices of refraction.
crown
Archimedes came across concept of density - that is MASS divided by VOLUME. For each substance this ratio is different but a CONSTANT for that substance. Thus the mass you are dealing with is irrelevant if the crown had the same ratio as the piece of pure gold then the crown was pure god, if it did not then the crown was not gold.
