Why do marbles become paler on grinding? Reflectance, spectroscopy, color, and particle size

The observed color of a material is due to interaction between light and matter. This interaction is more easily understood for transparent media than for solid opaque media. The theoretical aspects of the spectroscopy of solids are presented to explain the physical principles involved in such obser...
