I dont get it please helpThis is the chart they gave me i dont know if this will help in solving this but its worth a tryIndex of Refraction:Air: 1.00Water: 1.33Quartz: 1.54Diamond: 2.42
There are a family ( group ) of quartz minerals. Quarts is SiO2, but there also exists SiO4 and SiO6, and due to the different crystal structures and bonds, the quartz group ranges in density from 2.2 to 4.28 in density High quartz = Beta quartz has a average density of 2.53. This exists only at high temperatures and high pressures. Once the temperature decreases lower then 573 degrees Celsius, it is converted into low quartz which has an average density of 2.65 The reason that the conversion is so easily accomplished is that the difference between quartz and beta quartz is relatively slight. The bonds between the oxygens and silicons are kinked or bent in quartz and are not so kinked in beta quartz. At the higher temperatures the atoms move away from each other just enough to allow the bonds to unkink or straighten and produce the higher symmetry. As the temperature is lowered, the atoms close in on each other and the bonds must kink in order to be stable and this lowers the symmetry back down again.
