LIGHT. “As we move to the scale which is the realm of few nanometers to few hundred nanometers, the properties of light at different wavelength take hold, where light of different wavelengths, interact with molecular bonds, exchanging energy in elastic and inelastic absorption and scattering, interacting with and exchanging energy in the different wavelengths with rotation and vibrational energies of the molecules and their interplay with energy bonds, when the electrons in the valence band are shared between two or more atoms of molecules.”
