Transparent bodies and light scattering
Color and visual appearance. Transparent, translucent, opaque

Using a highly transparent glass prism, Newton decomposed and recomposed diaphanous sunlight . This transparency gave rise to the colorful scarf of Iris, messenger of the Gods revealing color to us. The rainbow also expressed the phenomenon we now call light dispersion [A 2 090] , i.e. the spatial (angular) separation of the constituent rays of a polychromatic light source as a function of their wavelength. These are the scaling relationships that govern the different interaction regimes between radiation and matter. These interactions can be grouped together under the single...
