REPUBLIKA KIDS -- Hello Kids... Perhaps you have been asked why the sky is blue, and when dusk turns red or orange. The answer most often sounds blue sky because of the reflection of the blue sea.

In fact, the color of the sky is caused by sunlight that emits all colors of visible light and passes through the Earth's atmosphere. Then why is the sky during the day blue?

As quoted from spaceplace.nasa.gov, the color in the sky comes from the main light in the solar system, namely the sun. If you look directly, sunlight looks white, but actually sunlight consists of all visible color spectrums, ranging from red to purple.

Sunlight that travels to Earth through the atmosphere is absorbed, reflected, and then transformed by various elements, compounds, and particles

Blue is scattered more than other colors because it moves as shorter and smaller waves. This is why we see blue skies most of the time. The atmosphere scatters blue light more than any other color.

Approaching the horizon, the sky fades to a lighter light blue or white. The sunlight that reaches the earth has passed through more air. As sunlight has passed through all this air, the air molecules have dispersed and re-streamed blue light many times in different directions.

In addition, the surface of the earth has reflected and scattered light. All these scatterings mix the colors together again so that we see more white and less blue.

Then why does the sky turn orange at sunset...
