Why is the sky blue? I know this is a question everyone has asked sometime in their life. I just now decided to research to find the real answer.
When sunlight reaches the atmosphere, all of the light is spread apart by particles in the atmosphere. The blue light is scattered more because of the shorter wavelengths it possesses. On the other hand, when the sky is a reddish orange color during the sunset, the blue light is spreading apart further to allow the red and yellow wavelengths through.
Also, when you are watching a sunset from the beach, it is way more vibrant because the light from the sun reflects off of the water vapor in the air making it bigger. I guess my next question will be…Why is the grass green? Visit this website for more information on sunlight. http://spaceplace.nasa.gov/blue-sky/
