In short, then … “sunlight, interacting with air molecules, dissipates into different colors. Of all colors, it is blue color that is best predisposed to dispersion. It turns out that it actually captures airspace. “.
Now let’s go more
Only children can ask such simple questions that a completely adult does not know how to answer. The most common question is tormenting children’s heads: “Why is the sky blue?”However, not every parent knows the correct answer even for himself. The science of physics and scientists will help to find it, trying to answer it for more than one hundred years.
For many centuries, people have been looking for an answer to this question. People of antiquity believed that this color is loved for Zeus and Jupiter. At one time, explanations of the sky of the sky excited such great minds as Leonardo da Vinci and Newton. Leonardo da Vinci believed that combining each other, darkness and light form a lighter shade blue. Newton associated a blue color with a cluster in the sky of a large amount of water drops. However, only in the 19th century did it manage to come to the right conclusion.
In order for the child to understand the correct explanation with the help of the science of physics, initially he needs to understand that the beam of light is a particle flying at high speed segments of an electromagnetic wave. In the stream of light, long and short rays move together, and by the human eye they are perceived jointly as white light. Penetrating in the atmosphere through the smallest drops of water and dust, they dissipate into all colors of the spectrum (rainbow).
John William Ray
Back in 1871, the British physicist Lord Rey noticed the dependence of the intensity of multiple light on the wavelength. The scattering of the light of the Sun on the heterogeneities of the atmosphere explains why the sky is blue. According to the law of the relay, the blue sun rays scatter much more intensively than orange and red, as they have a lower wavelength.
Air near the surface of the earth and high in the sky consists of molecules, which is why sunlight dissipates high in the air atmosphere. He reaches an observer from all sides, even from the most remote. The spectrum of multiple air of light is noticeably different from direct sunlight. The energy of the first is moved to the yellow-green part, and the second-to blue.
The more intense dispersion of direct sunlight, the more cold the color will seem. The strongest dispersion, t.e. The most short wave is in purple, longwave scattering red. Therefore, during the sunset, the territory of the sky remote from it seems blue, and the closest ones are pink or scarlet.
Dawns and sunsets
During sunset and dawn, a person most often sees pink and orange shades in the sky. This is due to the fact that the light from the sun passes very low to the surface of the earth. Because of this, the path that the light needs to be made during sunset and dawn is much longer than during the day. Due to the fact that the rays go the largest way through the atmosphere, the main part of the blue light is dissipated, so the light of the sun and nearby clouds seem reddish or with a pink shade.
