Spectra of white light obtained with CD

Light refraction on  facets of cutted in brilliant geometry heavy glass

Double rainbow (single and double reflection inside the drop - colors are inverted)

Sunset over Ionic Sea (Itea, Greece): completive colors are created due to Rayleigh's scattering

Brewster's reflection (light polarization) and torsion of polarization plane in anisotropic polymer

Light refraction on snow crystals

Rainbow

Rayleigh's scattering in water with added drop of milk
