On a clear day the sky is blue to deep blue. At dawn and dusk the stretch of sky nearest the sun changes to shades of red, orange and yellow. The color of the sky is primarily determined by the way air molecules scatter ... More »

There are many proximate causes for changes to the color of the sky, but they all involve the way light is diffracted through the air. Light from the sun can be bent as it moves through the Earth's atmosphere, and the wa... More »

The sky is blue as a result of Rayleigh scattering. Rayleigh scattering represents the high frequency of gas molecules hitting and absorbing blue light. As the horizon turns pale, the blue light has to pass through more ... More »

Blue is a primary color and many objects in nature have a blue color, including cobalt compounds, the flames of burning sulfur, the sky and the ocean. In 1873, Levi Strauss and Jacob Davis applied for a patent for rivete... More »

A science project that explains the blue color of the sky at certain times of the day can be done by projecting a beam of light from a flashlight or a projector through a transparent container, like a large beaker or a j... More »
