What metallic metal is sky blue?

sky is blue because of the sun and water also the rotatilon of the earth What? 1. Outer space contains virtually no gas/dust to scatter light. Outer space is black. 2. The sky is blue because that's the colour of air (mostly nitrogen), which is not totally colourless. You can see this effect looking at distant (10 km-plus) mountains. They have a blue tinge (caused by the intervening air between you and the mountains) known as atmospheric perspective. 3. If the sky's colour was due reflection from the oceans, then it would be white above Antarctica, which is snowy white.


Can the sky be white?

The first steps towards correctly explaining the colour of the sky were taken by John Tyndall in 1859. He discovered that when light passes through a clear fluid holding small particles in suspension, the shorter blue wavelengths are scattered more strongly than the red. This can be demonstrated by shining a beam of white light through a tank of water with a little milk or soap mixed in. From the side, the beam can be seen by the blue light it scatters; but the light seen directly from the end is reddened after it has passed through the tank. The scattered light can also be shown to be polarised using a filter of polarised light, just as the sky appears a deeper blue through polaroid sun glasses. This is most correctly called the Tyndall effect, but it is more commonly known to physicists as Rayleigh scattering--after Lord Rayleigh, who studied it in more detail a few years later. He showed that the amount of light scattered is inversely proportional to the fourth power of wavelength for sufficiently small particles. It follows that blue light is scattered more than red light by a factor of (700/400)4 ~= 10.


Why are shadows shorter in the summer?

Shadows are shorter in summer because the sun is higher in the sky, resulting in a shorter angle between the light source (sun) and the object casting the shadow. This angle affects the length of the shadow cast. Additionally, the longer daylight hours in summer mean the sun is overhead for a greater portion of the day, further contributing to shorter shadows.

What color is the sky?

== == The sky appears to be blue as perceived by the human eye. This is because the light from the sky is a result of the sunlight scattering.The sky can change and appear lots of colors, such as red, orange, yellow, pink, purple (at sunrise and sunset) and black (at night).the colour of the sky is black but depending on the amount of sunlight approaching the earth and on the quantity of scattering it's colour changes. during the day time when it is dawn the colours of all other wavelenghts are scattered other than blue so sky looks light baby blue during the mid noon all the wavelenghs pass through the earth atmosphere and that is why the sky looks white or bright yellow( the average of all wavelenghts). during night since there is no sunlight the scattering does not take place and so it looks black.

Why can't the sky in the green colour?
