The sky is blue because
When the sky is clear and blue it is because blue light is reflected by molecules in the air from the sun a lot more than they are reflecting red light. The sunlight has all the colors of the range in it; when reflected through a prism or these little compounds, you see different colors. Those colors you see in the sky are derived ...view middle of the document...
At sunset, the blue is then out of your type of sight.
This is a really deep matter. You’ve to comprehend perhaps and prisms which kinds of compounds reveal the different shades. So many actually technical things to consider. In about 1859 man called John Tyndall took measures in the name of science to explain the sky’s color. He proved that light passes through clear water and acts like a prism by polarizing the light with benefits and particular attributes. This is know as the Tyndall Effect, frequently recognized to physicists as Rayleigh scattering–after Lord Rayleigh, who analyzed it in greater detail a couple of years later. His tests demonstrated, and showed, the number of light scattered is inversely proportional to the fourth power of wavelength for sufficiently small particles. It followa a blue pattern
