Answer 1

Синее так голубое какая разница

Answer 2

Why is the Sky Blue?

The sky appears blue during the day due to a phenomenon called Rayleigh scattering. This occurs when sunlight interacts with the Earth's atmosphere. Here's a simple explanation of why the sky appears blue:

1. Sunlight is made up of a spectrum of colors, including red, orange, yellow, green, blue, indigo, and violet. These colors have different wavelengths, with blue light having shorter wavelengths than red light.

2. When sunlight reaches the Earth's atmosphere, it encounters tiny particles such as molecules and tiny dust particles. These particles are much smaller than the wavelength of visible light.

3. The blue light from the sun is scattered more than the other colors of light because it interacts more with the molecules in the atmosphere. This scattering causes the blue light to be redirected in different directions.

4. As a result, when we look up at the sky, we see the scattered blue light coming from all directions. This is why the sky appears blue to our eyes.

It's important to note that the sky can appear different colors at different times of the day. During sunrise and sunset, for example, the sky can appear red or orange. This is because the sunlight has to pass through more of the Earth's atmosphere, and the shorter blue and green wavelengths are scattered out of our line of sight, leaving the longer red and orange wavelengths to reach our eyes.
