MEMPHIS, TN (WMC) - One of the most popular questions when it comes to weather is, ‘why is the sky blue?’ If you have ever wondered why, check out this breakdown.
Let’s start with white light or sunlight, which appears to us as white, but it is actually all different colors. When light shines into a prism, light is separated into all different colors.
Light mostly travels in a straight line unless there is something in the way. If there is something in the way, light will bend, scatter, or reflect.
Once sunlight reaches the Earth’s surface, some of it gets absorbed and the rest scatters in many different directions. It scatters due to the particles and gasses in the air.
Blue light gets scattered more than the any of the other colors and it travels as shorter and smaller waves. This is why our eyes see the sky as blue most of the time.
