How light reflects from a mineral's surface
WebThe reflection coefficient is r = (n-1)/ (n+1) where n is refractive index of glass. The light is travelling in air before it is incident on glass. Now n = 1.5 for glass and r = 2/5 or 0.4. The … WebSome minerals are bright with reds, greens, blues, and yellows. These colors are determined by the main element s in a mineral’s chemical formula. For example, copper (Cu), will cause azurite to be blue and malachite to be green. Fig. 3.2.2. Rock containing green malachite and blue azurite.
