I Wonder Why – Why The Sky Is Blue In Color?

Blue skies

Why is the sky blue?

● The Earth’s atmosphere is filled with trillions of tiny dust particles. These particles

are too small to be seen with the human eye.

● As the light from our Sun shines into the atmosphere, most of the colors are able

to reach the Earth’s surface uninterrupted.

● However, because blue light has a wavelength that is the same size as the

particulates in the air, this light is scattered in every direction. This blue light

bounces from particulate to particulate until it eventually reach your eyes.

● This blue light originated with the Sun, was bounced around in the sky many

times, and then eventually reached your eyes.

● Now, during sunrise and sunset, the light traveling through the atmosphere is longer

at the horizon, then if you were to look up high in the sky. There is more dust

particles at the horizon, so that is why you see such pretty colors like red,

oranges and yellows.
