Почему небо голубое???


Ответы на вопрос




Why is the sky blue?
The sky appears blue due to a phenomenon called Rayleigh scattering. When sunlight passes through the Earth's atmosphere, it interacts with the molecules and particles in the air. The molecules in the atmosphere, particularly nitrogen and oxygen, scatter the sunlight in all directions. However, the shorter wavelengths of light, such as blue and violet, are scattered more than the longer wavelengths, such as red and orange. This scattering of shorter wavelengths is what gives the sky its blue color.
Rayleigh scattering is the process by which the shorter wavelengths of light are scattered more than the longer wavelengths when they interact with particles smaller than the wavelength of light. This scattering is inversely proportional to the fourth power of the wavelength, which is why shorter wavelengths, like blue and violet, are scattered more than longer wavelengths, like red and orange.
It's important to note that the color of the sky can vary depending on various factors such as the time of day, atmospheric conditions, and the observer's location. For example, during sunrise or sunset, the sky can appear red or orange due to the scattering of sunlight by particles and molecules in the atmosphere over longer distances.
In summary, the sky appears blue because of the scattering of shorter wavelengths of light, particularly blue and violet, by the molecules and particles in the Earth's atmosphere.
