Why is the sky blue? Why is the sky blue?

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.

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 scattering of sunlight by the atmosphere makes the sky appear blue as we see.

When light travels through the air, it inevitably encounters gas molecules and other particles in the air. These particles absorb, reflect, and scatter light, and it is these physical processes that make the sky blue on a clear day.

Because blue is pure, the sky is the purest.

There is the protection of the atmosphere, and raindrops.

is responsible for the wavelength of blue light.

The reason is simple, the scattering of sunlight by the atmosphere makes the sky appear blue as we see.

The Earth's surface is surrounded by an atmosphere, and when sunlight enters the atmosphere, air molecules and particles (dust, water droplets, ice crystals, etc.) scatter sunlight around. Sunlight is composed of seven kinds of light: red, clear, yellow, green, blue, indigo, and violet, with red light having the longest wavelength and violet light having the shortest wavelength. Color light such as red light, which has a longer wavelength, has the greatest transmittance and can directly penetrate particles in the atmosphere to the ground.

Blue, indigo, violet and other colors with shorter wavelengths are easily scattered by particles in the atmosphere. In the shortwave band, blue light has the most energy and scatters the most light waves, so the sky we see appears blue.

The blue sky is white and white clouds are drifting". I believe everyone has a feeling for this beautiful scenery. So why is the sky blue?

Why are clouds white? Not everyone can say why for this wonderful physical phenomenon. In fact, this beautiful sight we are viewing is the result of the combined action of atmospheric molecules, water droplets, other particles, and sunlight in the sky.

This is due to the scattering of sunlight by the air. In addition, the color of the sky depends on your state of mind, the sky is generally blue, azure blue, although occasionally a little gray, but soon it can pass, I think your sky will always be blue.!

When sunlight enters the atmosphere, red light, orange light, yellow light and other long-wavelength color light can directly pass through the atmosphere to the ground, and blue light and other short-wavelength color light will be scattered, so that the sky is blue light in all directions.

Hope it helps.

Generally due to the scattering of light ...

Air molecules tend to scatter blue-violet light with shorter wavelengths.
