Does Rayleigh scattering explain the Blueness of Sky?

WebThe more pigment you have, the darker your eyes will be. Blue, grey, and green eyes are lighter because they have less melanin in the iris. Most people in the world will end up with brown eyes. The next most common colors are blue and grey, and green is the rarest color. Besides giving our eyes color, melanin helps protect them from the sun. WebRayleigh scattering gives you a blue-white color, factors being listed above including the solar spectrum, the Rayleigh behavior, and the sensitivity of the eye, but not a really blue color. 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. song techno remix
