“Why is the Sky Blue? Physics Explains the Phenomenon”

YOGYAKARTA – When it’s sunny outside, of course, if we look up at the sky, of course it looks blue with beautiful white clouds. But have you ever thought why the sky is blue?

Exactly during the day, especially when the weather is bright, so the color of the sky will appear blue. In fact, this one event is the same as the blue ocean incident. If you look at it from a distance, it will appear blue, but if you approach it, the water will appear clear.

Of course, curiosity arises in our heads, how can the sky produce a blue color? In fact, this matter can be explained in an objective way. If we previously learned about the refraction of light, we can know the blue color of the sky through one of physics.

The reason why the sky is blue

There is a Short Wave of Light

The source of light in the universe is the Sun. Its light, which is white in color, radiates to the planets that revolve around the Sun, including Nature where people live. When the sun’s light radiates to Nature, the white light will pass through the Earth’s atmosphere.

In physics practice, the atmosphere can be likened to a mirror prism. Where the Earth’s atmosphere which contains various gases such as carbonium, nitrogen, acids, and others will cause light to be fragmented when passing through it.

The divided light will change into different waves. There are long waves and there are some short waves. The distant light waves will change to yellow, orange, and also red. Meanwhile, short light waves will turn blue and green. Such motives can be obtained by the retina of our eyes.

Short Waves of Light Scatter in the Sky

If distant light waves could be carried straight up to great distances, then short waves would mostly fall apart in space. Things like that can make most of the sky blue compared to other colors. The short-wave light actually seems to envelop the Earth, so that the big sky will also appear blue.
