Why isn t the sky green? 30

Because photons are scattered by air molecules as they travel through the atmosphere, sunlight turns blue after being scattered. Note that it is the scattering of light, not the dispersion of light.

Because there are no trees planted in the sky, it is not green.

The sky is sometimes green for the following reasons:

The green, blue, and chorus orange central light in sunlight is more susceptible to the scattering of dust and water vapor in the air, so the sky appears blue. There is less dust on the beams of the sea and the water vapor content is also reduced by the sunset, so the sunlight scatters very little, while the density of the atmosphere is sparse and dense, and the sunlight is refracted the most, among which green, blue, and purple are the most refractive, so the sky appears green. Reduced aerosols in the air after thunder, rain, and hail also lead to a decrease in scattering, which is green.

Wild Yu Regiment.

The green sky is a type of dispersion phenomenon. Before the heavy rain comes, the clouds will gather some dust particles, ice crystals and thick water vapor, when the light penetrates, it will scatter, the sunlight penetrates the atmosphere to the ground, and is scattered by these dust particles, ice crystals, water vapor, etc.

And yellow and blue can be mixed together to make green, so when the blue light and yellow light scattered from the sky come together, green will appear, and the two colors will be superimposed, and the sky will become a green sky.

Scientific Principles:The reason for this is that the water droplets and ice particles in the wind bending storm are extremely dense and almost connected, and the blue light and some green light are easy to scatter due to the relatively short light wave and poor penetration. The blue of the water droplets, the ice droplets, and the yellow of the setting sun, make the sky look like green when you see it clearly.

In other words, it is a rare and complex optical reaction of severe convective weather encountering sunset.

First, the earth is surrounded by the atmosphere, and the sunlight must penetrate the atmosphere in order to reach the ground where we live.

Second, sunlight is composed of a variety of wavelengths of light (lasers are mostly single-wavelength rays), and each wavelength basically represents a visual color, and mixed light is visible to humans as white.

Third, 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 colors of light that are shorter than Sun Nazhi's are scattered in all directions, making the sky appear blue.

Fifth, the grass in the wild grassland is very high, and the cattle and sheep are flooded into the sea of grass when they graze, and the Min's wind drafts low cattle and sheep. Now overgrazing, I'm afraid I won't see it.

The sky is blue. Because of the ozone, the ground is -- needless to say. Blue

After thunder, rain, and hail, the amount of aerosols suspended in the air decreases, so the scattering decreases, which is probably similar to the green reason for the sunset over the sea below.

The sunset over the sea is sometimes green because:

The green, blue, and purple central light in sunlight is more susceptible to the scattering of dust and water vapor in the air, so the sky appears blue. There is less dust at sea, and the water vapor content is also reduced by the sunset, so the sunlight scatters very little, and the density of the atmosphere is sparse and dense, and the sunlight is refracted at the top, among them, green, blue, and purple are the most refractive, so the sky appears green.

Why is the sky blue? Not other colors, do you know the answer?

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.

The sun's rays are made up of 7 colors of light.

When sunlight enters the Earth's atmosphere.

Blue and purple light rays are most easily refracted and reflected.

And the purple light is not easy for us humans to see with the naked eye.

That's why the sky is blue.
