The color of the sky. The colors of the sky change over time For the sky is blue. Best in the morning and in the evening the sky is orange red. This phenomenon occurs because of the "krachoeng light" (Scattering of light) light waves, each wave length, color, size. When air molecules are reconciled, it will result in krachoeng of different light. Factors of krachoeng of light Dimensions length Waves the size of obstacles. The angle that the light falling on the quantity of air suspension in the atmosphere.The daytime sky. The sun angle slope to the surface of the Earth. Light traveling through the atmosphere, and is a short distance. There are little obstacles obstructing the light purple and indigo blue. There are smaller than the wavelength of the molecules of air, thus krachoeng to the sky in different directions. We see the sky is blue. In areas where there is less air pollution, such as island in the sea, we can see the blue sky. Best in areas where pollution is much suspension in the air. The Green and yellow light will come to krachoeng with, we see a light blue sky.The morning and evening skies Solar slope angle with the surface of the Earth Light traveling through the air mass is long distance. There are many obstacles that day purple indigo and light blue. Unable to travel through obstacles to get everything krachoeng just lighting yellow, Orange and red sections. Krachoeng on the Plains along the beam, we see the Sun and the nearby sky is red. Evening sky over red dawn now because of the high temperature in the afternoon. Make more dust in the air in the morning with dust in the air is holding water in a wash in the morning darkness. So the evening has more than krachoeng of the red light in the morning.
