WebThe true color of the sky, without any atmospheric scattering, is actually black. However, due to the scattering of sunlight by the Earth’s atmosphere, the sky appears blue during the day. This phenomenon is known as Rayleigh scattering, named after the British scientist Lord Rayleigh who discovered it in the late 19th century. WebThe 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. Consequently, when there are more …

WebPeople with hazel eyes often have a non-uniform pigmentation of their iris as their colour is a mix of the 'default' colour blue, (which is not a result of a blue pigment but of a total lack of pigment, the blue being caused by rayleigh scattering), and the addition of a bit of brown melanin pigment, most often at the edges of the iris. WebApr 10, 2024 · In conclusion, the blue color of the sky is due to the scattering of sunlight by the Earth's atmosphere, specifically the scattering of shorter, blue wavelengths of light.

WebMar 5, 2024 · Green eyes are interesting because they combine light scattering and two kinds of pigment: They hold slightly higher amounts of eumelanin than blue eyes, as well as some pheomelanin. WebFeb 21, 2008 · Scattering of light (Tyndall effect and, closely related, Rayleigh scattering) can thus be observed quite frequently. The iris of the human eye does not contain any blue pigment or dye. The turbid front layer, if it contains no or only little melanin, appears blue in front of the dark back layer due to the preferred scattering of light with short wavelengths.
