Health is wealthWhy is Glass Transparent?
When a light encounters a material, it can interact with it in different ways. These interactions depend on the nature of the light and the nature of the material. For instance, light falling on the leaf encounters many pigment molecules, predominantly chlorophyll. These molecules absorb light from the red and blue ends of the visible spectrum. The remaining light is scattered back because molecules in a leaf are lightly packed and so we see a green leaf. Glass has properties of both as solid (its molecules don’t move much) and a liquid (the molecules are not arranged in a order). Molecules in a Glass are not packed into a tight lattice and unless tinted does not contain molecules that capture light with a particular energy. Hence, when light encounters glass, most of it passes straight through making Glass look transparent.
