One of the main questions that curious teenagers often ask about the ordinary world is, "Why is the sky blue?" But despite the vastness of  this question, there is a lot of confusion and wrong answers to talk about. Because oxygen is a blue gas. Due to the blue color of sunlight, the correct response is often completely ignored. In fact, the explanation that the sky is blue is the result of three basic factors: daylight is made up of different frequencies of light, and the environment in the world scatters different frequencies of light to different amounts. It's composed of particles, and the responsiveness of our eyes. If you establish these three, blue skies are inevitable. This is how it all comes together. 
Daylight consists of a relatively diverse range of light with different shades... To say the  least! Our Sun's photosphere  is extremely hot, nearly 6,000K, and emits a broad spectrum of light, from the highest energy bright light to visible light, from violet  to red and beyond into the infrared  range. doing. The highest energy light is also the shortest frequency (and high return) light, while the low energy light has a longer frequency (and lower frequency) than its high energy partner. The explanation for all the light components, when you look at how crystals separate sunlight into individual parts,  is  that red light has a wider frequency range than blue light. The more limited the frequency of light, the better it will be dispersed, as it is much more modest than the frequency of light itself. In fact, violet light in the short-frequency limit of human vision is subject to a regulation known as the Rayleigh derivative, which states that it is many times more scattered than  red light in the long limit. frequency limit.  Although sunlight falls everywhere on the dayside of the Earth's environment, the redder frequencies of light are easily scattered by 11%. Because it's easy for your eyes to have a violet light. 
At points where the sun is overhead, the entire sky is blue for this purpose. These headings have more air (and therefore more blue light), so they appear brighter blue the further they are from the Sun. Everywhere you look  you can see scattered light from daylight hitting the entire climate between your eyes and the beginning of the universe. This has a fascinating effect on the shadows in the sky, depending on where the sun is and where you are looking.
