Refractive index zircon
WebType - Metamict (lower RI): sometimes called low Zircon: 1.777-1.79 Metamict (lower refractive index) Zircon is usually found as river-worn pebbles Critical Angle: 34.40° Specific Gravity: 3.9-4.71 Cleavage: Imperfect 2 directions. Fracture: Conchoidal, very brittle. Dispersion: .038 Heat Sensitivity: Yes, in my experience WebThe index of refraction for zircon is given as 1.923 in Table 1.1, and c is given in Equation 1.1. Entering these values in the equation gives v = 3.00 × 108m/s 1.923 = 1.56 × 108m/s. Significance This speed is slightly larger than half the speed of light in a vacuum and is still high compared with speeds we normally experience.
