My favorite color is blue! It lies between violet and green! Do you like blue?
Yes blue reminds me of the ocean and the sky. Does it also remind you of nature?
Yeah! The clear sky during the day is blue because of the effect know as Rayleigh scattering!
Rayleigh scattering? I am not familiar with this. Would you mind expanding on what it is?
Rayleigh scattering
Rayleigh scattering ( ), named after the nineteenth-century British physicist Lord Rayleigh (John William Strutt), is the predominantly elastic scattering of light or other electromagnetic radiation by particles much smaller than the wavelength of the radiation. For light frequencies well below the resonance frequency of the scattering particle (normal dispersion regime), the amount of scattering is inversely proportional to the fourth power of the wavelength.
Rayleigh scattering results from the electric polarizability of the particles. The oscillating electric field of a light wave acts
Blue
Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between violet and green on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering.
