Refractive index vs specific gravity
WebSpecific gravity: 3.24 Refractive index: 1.64 - 1.68 Birefringence: .02 Crystal or stone size: massive Comments: The aluminum silicate mineral sillimanite, used in the manufacture of spark-plug porcelain and other refractories, has the same chemical formula, as andalusite and kyanite. Also called fibrolite because of its long, needlelike ... WebThe refractive index of X-rays is slightly less than 1.0, which means that an X-ray entering a piece of glass from air will be bent away from the normal, unlike a ray of light, which will be bent toward the normal. The equation n = c / v in this case indicates, correctly, that the velocity of X-rays in glass and in other materials is greater ...
