Why Is The Sky Blue ??? Here's Answer

One of the most commonly seen sights is the sky blue, yet what's not widely know is what makes it sky blue in color


                 The sun emits light travels through space toward Earth. Because space is vacuum ( for example it has not atmosphere , the light remains largely undisturbed until it nears the earth, whose atmosphere is made up of a mixture of gas molecules, The closer you get to the earth  , The thicker the atmosphere.
                 Light from the sun appears while but is in fact a comi-bnation of colors, and the range of these colors that are visible to human eye----- from red to violet, by way of orange, yellow, green, blue and indigo is shown when light is passed through a prism. these different colors have different wavelength and energies, with violet having shortest wavelength and highest energy and red having the longest wavelength and lowest energy 
               As Light  Hits the Earth' atmosphere the different colors react in different ways. Some of them get obsorbed by the gas molecules while others do not. Most of the longer wavelength colors ( such as red and orange ) pass straight through the atmosphere and are unaffected, While many of shorter-wavelength colors ( such as violet and blue ) get absorbed by the gas molecules , Because the wavelength (i.e., the distance between the peaks of each wave) of these colors are similar in size to diameter of an atom of oxygen. The gas molecules then radiate these colors and scatter them across the sky, thats why we seen blue sky.
