Why are angels so blue and clouds so white 5

It's been a long time since I've seen a blue sky and white clouds. The sky is always gray, and the clouds are always dark.

It's poetic, don't you think it's beautiful?

The sky is blue because of the scattering, and the white clouds are white because of the water vapor.

1. The reason why the sky is blue: The scattering of sunlight by the density fluctuation of the air itself forms a blue sky. In 1910, Einstein used the then newly developed entropy (chaos.

The presence of O3 in the atmosphere, O3 reflects blue light.

I don't know, because I've been taught this way since I was a child. If I say it's red, people will say I'm sick. Hehe, the following is someone else's correct answer, you can refer to it.

1. The composition of the atmosphere is not single, and it is divided into many layers from the outside to the inside, each layer and each component will correspond to reflecting, refracting, and scattering a specific wavelength of light, and the blue, violet, indigo and other colored light with a shorter wavelength are scattered in all directions, making the sky appear blue.

2.The reflection of water droplets in the full spectrum is, of course, white! At sunset, the light itself is red, and the clouds are red. As with white paper, the color of the light is the color of the light, because it reflects all the visible spectrum.

1: Because the atmosphere in the sky absorbs all the color light from the sun and not the blue light.

The blue light reaches the ground and is seen by the human eye! That's why people think the sky is a basket!

2: And the clouds will be white.

This is because clouds are formed by the accumulation of a large amount of water vapor.

Water can pass through all colors.

When a large number of water droplets gather together.

It will form white.

And the unnamed cloud.

Because the sea is blue, mapping.

Formation of clouds. If we know evaporation, sublimation, condensation, and condensation, it is easy for us to understand how clouds are formed. The water in the ocean, lakes, plant surfaces, and soil evaporates all the time, turning into water vapor and entering the atmosphere. Moist air containing water vapor rises upwards for some reason.

During the ascent process, as the surrounding air becomes thinner and thinner, the air pressure becomes lower and lower, and the volume of the rising air expands. When it expands, it dissipates its own heat, so the temperature of the rising air decreases. When the temperature decreases, the ability to contain water vapor becomes smaller and smaller, the saturated water vapor pressure decreases, the water vapor in the rising air quickly reaches a saturated state, and the temperature decreases again, and the excess water vapor attaches to the condensation nucleus suspended in the air and becomes small water droplets.

If the temperature is lower than 0, the excess water vapor condenses into ice crystals or supercooled water droplets. They are gathered together, supported by updrafts, and float in the air as clouds that we can see.

The sky is blue :

There are many tiny dust, water droplets, ice crystals and other substances in the air during the weather, and when sunlight passes through the air, the longer wavelength of red light, orange light, and yellow light in the sunlight can penetrate it.

The atmosphere shines directly to the ground, and the blue, violet, indigo and other colored light with a short wavelength are easily blocked by particles suspended in the air, so that the light is scattered in all directions, making the sky appear blue.

The clouds are white: This is related to the density of water vapor in the clouds.

Because dust is needed in the condensation nuclei of clouds, dust is gray and water is colorless. So so.

1.When sunlight hits the Earth's atmosphere, blue light is most easily separated from other colors, diffused into the air, and reflected back. Other colors of light are very penetrating and penetrate the atmosphere to the earth, so we can only see the blue light in the daylight when we look at the sky.

2.The multiple reflections, scattering, and absorption of sunlight by clouds generally make clouds appear black, white, and grayscale. However, sometimes colored clouds appear due to refraction, which is mainly seen in the refraction of light rays from behind the clouds and into our eyes, resulting in dispersion - morning glow and sunset!

Haha, satisfied?

That's what you see.
