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 »

The sky appears blue because of the scattering of sunlight by atmospheric molecules, or Rayleigh scattering. Rayleigh scattering results in a blue sky because it is most noticeable at shorter wavelengths. 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 »

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 physical process of scattering causes the sky to appear pink at times and other colors too. During this process, tiny particles of light are bounced off air molecules. Wavelength, time of day and laws of quantum mech... More »

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 »
