This is a question we all ask when we\u2019re kids: Why is the sky blue?\n
Many think that it\u2019s reflecting the color of the ocean, but that\u2019s a huge myth!\n
It\u2019s not a short answer, but it is a simple one that\u2019s easy to understand.\n
So let\u2019s find out, once and for all, why the sky is blue!\n
\n
The color that comes from the sun is a white light that is a mixture of all the colors of the rainbow.\n When the sunlight gets to the atmosphere of Earth, it is scattered in every direction by the gases and particles in the air.\n It was Isaac Newton who discovered that a prism could be used to separate the different colors and form a spectrum.\n He further proved that it wasn\u2019t the prism coloring the light by refracting the light back together.\n Each shade of color consists of different wavelengths.\n Red has the longest waves, and violet has the shortest waves. Short wavelengths are scattered more strongly than long waves.\n This is because of our eyes! We distinguish colors by using cones in our retinas, which are photo receptor cells.\n Each retina contains 5 million cones of 3 different types which specialize in different colors. \n Specifically, the 3 different types of colors are red, blue, and green which are the colors our eyes respond the strongest to.\n Even though violet is the shortest, it is absorbed by the atmosphere making there less violet in the light.\n On top of that, our eyes are less sensitive to violet because of our color receptors.\n That leaves us to see a blue sky, since blue is the second shortest wavelength!\n So on a clear day with no clouds, we will see a blue sky because the molecules in the air scatter blue light more so.\n Red light during the day doesn\u2019t quite scatter in the daytime.\n When the sun goes down, all of this changes. Sunsets are typically vibrant colors of reds, oranges, pinks, and purples.\n When the sun is going down, the blue light is scattering where the sun is moving, and it\u2019s blue out of our line of sight.\nThen why don\u2019t we see a violet sky?\n

Why are sunset\u2019s different colors?\n
