Sunset in Cades Cove

Sunsets are one of those wonderful things that happen only once a day. Why they are so colorful is very interesting. Sunlight is made up of red, green, and blue light waves. Blue light waves are shorter than red ones. During the day the sunlight passes through less moisture and dust in the atmosphere than it does in the evening or morning making the shorter blue light waves more visible. When the sun is closer to the horizon line (morning or evening) the longer red light waves are seen because of the increased moisture and dust the light must travel through. Remember that the best sunsets usually happen when there are clouds in the sky that reflect these warm light waves.
