In the eye, this effect occurs in the top layer (stroma) of the iris. The blue optical effect of ... WebScattering processes. If the size of the scattering particles is smaller than the wavelength of light, then the Rayleigh theory applies. If the size of the scattering particles approaches the wavelength of light or exceeds it, then the complex Mie scattering theory applies and permits scattering of colors other than blue; white is scattered at the largest sizes. howard hanna krall real estate lebanon paWebThe colors we see in the sky come from sunlight that is scattered by molecules in the atmosphere.This process is called Rayleigh scattering. Nitrogen and oxygen make up most of the molecules in our atmosphere, but any gas or aerosol suspended in the air will scatter rays of sunlight into separate wavelengths of light.

"WebSadly, all gases act as Rayleigh scatterers and would give blue skies in the absence of dust or aerosol. The exceptions are when gaseous components absorb light, like chlorine or nitrogen dioxide, to give a coloured sky. Dust and aerosol also colour. The thin Martian atmosphere is pink from its high dust content. " - Rayleigh scattering and eye color
