Question

Have you ever wondered why sky is blue?????

Answer 1

The sky is blue because our atmosphere is 75–80 percent nitrogen, which emphasizes the blue in sunlight.

The sky is black at night because the universe is rapidly expanding. Everything is moving away from us, and the stars that are farthest from us are moving away so rapidly that they can’t be seen. The light leaving them and headed for us hasn’t reached us yet. And never will.

hope you understand

⏭️A lot of other smart people have, too. And it took a long time to figure it out!

❤️The light from the sun looks white. But it is really made up of all the colors of the rainbow.

❤️When white light shines through a prism, the light is separated into all its colors. A prism is a specially shaped crystal.

❤️If you visited The Land of the Magic Windows, you learned that the light you see is just one tiny bit of all the kinds of light energy beaming around the universe--and around you!

❤️Like energy passing through the ocean, light energy travels in waves, too. Some light travels in short, "choppy" waves. Other light travels in long, lazy waves. Blue light waves are shorter than red light waves.

❤️All light travels in a straight line unless something gets in the way and does one of these things:—

reflect it (like a mirror)

bend it (like a prism)

or scatter it (like molecules of the gases in the atmosphere)

⏭️Sunlight reaches Earth's atmosphere and is scattered in all directions by all the gases and particles in the air. Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.

⏭️Closer to the horizon, the sky fades to a lighter blue or white. The sunlight reaching us from low in the sky has passed through even more air than the sunlight reaching us from overhead. As the sunlight has passed through all this air, the air molecules have scattered and rescattered the blue light many times in many directions.

Also, the surface of Earth has reflected and scattered the light. All this scattering mixes the colors together again so we see more white and less blue.
