Nephrite refractive index
WebWell, let's see. we will , let's see, what we calculated x is that refractive index, let's get the color right, refractive index of glass with respect to water and notice that that is equal to c divided by 1.33 so what's 1.33, that's the refractive index of water with respect to vacuum. and what's this 1.5, that's the refractive index of glass ... Some forms of actinolite are used as gemstones. One is nephrite, one of the two types of jade (the other being jadeite, a variety of pyroxene). Another gem variety is the chatoyant form known as cat's-eye actinolite. This stone is translucent to opaque, and green to yellowish green color. This variety has had the misnomer jade cat's-eye. Transparent actinolite is rare and is faceted for gem collectors. Major sources for these forms o…
