I wonder why the sky is blue?

First of all, understand how light works, as light travels from the sun, it moves up and down like ocean waves, and when the wavelengths come together, we appear as if they are white.

Because the sea is blue, the sky is like a mirror, reflecting the appearance of the sea, and the sea is the upside-down sky, and the sky is also the upside-down sea.

First of all, we understand the principle of the scale of light, when light travels from the sun, it moves up and down like ocean waves, and when the wavelengths are gathered together, we look as if we are white-colored.

Due to the ozone layer in the atmosphere.

Therefore, we see that the sky is through the blue stinky layer of the former tomb.

That's why it's blue. Hope.

Sunlight is composed of seven types of light: red, orange, yellow, green, cyan, blue, and violet. Among the seven types of light, cyan, blue, and violet wavelengths are shorter and are easily scattered by air molecules and dust.

The sea water is blue, the earth 3 4 is water, and the refraction of the sea water makes the sky appear blue.

The dispersion of sunlight through the atmosphere.

with the phenomenon of "scattering".

When sunlight passes through the air, the red light, orange light, and yellow light with longer wavelengths in the sunlight can penetrate the atmosphere and directly hit the ground, while the blue, violet, and indigo colors with shorter wavelengths are easily blocked by particles suspended in the air, so that the light scatters in all directions, making the sky appear blue.

The word count is out of range, and the following ** is very detailed.

When sunlight hits the earth, through a series of actions of the atmosphere, it is blue that is scattered into the human eye.

The color of the air, the sky is pitch black when you look at it from space.

It's geography. It is related to atmospheric refraction.

The sky was originally colorless, but due to the dispersion of the sun's rays, it had color. And that's why the sky looks dark at night. At night, the sun does not shine on this half of the earth's sky, and without strong sunlight, the sky has no color, and some, it is only black.

In clear weather, atmospheric molecules are very small particles, which are conducive to the scattering of short-wave light, and the short-wavelength blue and violet light in sunlight are easily scattered through the atmosphere, and the sky looks blue.
