Скачать или смотреть Why does the sky appear blue? A simple scientific explanation

The sky appears blue due to a phenomenon known as Rayleigh scattering. Here is a simple detail of this scientific phenomenon:

Composition of solar light: Solar light consists of a group of colors, which is what we see as white light. These colors include red, yellow, green, and blue, in addition to other colors.

Light scattering: When solar light enters the Earth's atmosphere, it interacts with air particles, dust, and fine particles floating in the air.

Rayleigh scattering: Molecules in the air (such as nitrogen and oxygen) begin to scatter blue light more strongly than other colors. This happens because blue light has shorter wavelengths and is more intense, making it more likely to be scattered when it hits air molecules.
Observing the color of the sky: We see the sky as blue because scattered blue light comes from all directions in the sky, and reaches our eyes from every direction. This large dispersion of blue light is what gives the sky its beautiful blue color that we see every day.

This is the phenomenon that explains why the sky appears blue when we look at it.
