Optical phenomena happen when light and matter interact. Reflection, refraction, absorption, scattering and interference of light are the main factors responsible for these events. Reflection makes it possible for us to see objects around us, and refraction occurs when light changes speed as it passes through transparent media. Absorption happens due to certain pigments. Nature is full of optical events such as Northern Lights, Mirage, Crepuscular Rays, Anti-Crepuscular Rays, Solar Halo, Rainbow, Pillars of Light, Iridescent Clouds and Belt of Venus. These are proofs of the interaction of light with matter, being true examples of optical wonders.
