why is the sky blue?

Why is the sky blue? The blue of the sky reflects the light from the sun on Earth. As the light waves scatter more than the red, yellow and green light waves, making the blue wavelength more visible, the sky looks blue to our eyes.


In order for light to scatter light, it must have some color. The color of the light itself is called its frequency or wavelength. When light travels, waves of frequency occur. Each color has its own wavelength.


For the human eye, the blue wavelength is most prevalent. Light traveling at this wavelength passes through the cornea of the eye and refracts out of the retina, then to reach our brains, which convert it to a visual representation.


Because blue light travels further from the sun than other colors, it takes longer to reach our eyes and refracts through our cornea more easily. This means that it is the shortest wavelength of all the colors that the eye can see, and thus makes blue the most prominent color of the light spectrum.


But the light waves do not stop there. Once they hit the eye, our brain interprets the light waves as colors: red, orange and yellow are three of the basic color categories we perceive light as.


So, if we want to know what is the color of the sky, then we need to answer the question How does the sky look blue? We need to know the wavelengths of different colors that it is possible to perceive, and we also need to know the speed of light itself.


Light travels at a certain speed relative to the sun’s movement, and it moves faster in the daytime than it does at night. Thus, the sun would appear blue if the light was traveling at the same speed it moves during the day. If light were moving slower, the light would appear orange, yellow or red.


So, if we want to find out why the sky appears blue, we should measure the wavelengths of light and their speeds and determine how the sun appears when it is traveling at its fastest. At the same time, we need to determine the speed of light when it is traveling at its slowest, so we can compare it with the rate of light in daylight. We will be left with the answer to How does the sky appear blue. by comparing the wavelengths to the speeds of light.


Light travels at different speeds on different days, because the sun rises and sets in different places. Thus, if you want to learn the color of the sky, you need to find out the wavelengths of light that it can detect at different times of the day. If it detects the light at noon and travels at a speed of light, it will not appear blue during the day. If it detects the light at midnight and travels at the slowest slow speed that it travels at during the night, it will not appear blue.


The wavelengths of light and their speeds are not the only factors that affect the colors that light travels. The atmosphere, gravity, atmospheric pollution, and even the sun’s position in the sky can change the way we see the light we see. and change the way we perceive light. In some cases, the color of the light is produced in the same way.


When green light travels through air, the electrons in the atoms are excited. This changes their energy. As long as the green light continues to pass through, these electrons are always in an excited state, giving the green light the color we normally associate with it. Because this process continues, this means that the green light is the longest wavelength of light that our eyes can detect. However, if the light stops, the green light will become blue, while the other light waves become red, orange, yellow, or even violet.


There is an interesting phenomenon that happens when white light passes through water. In this case, the wavelength of the light changes depending on whether it travels at the fastest or slowest speed, and the light is emitted in a different color depending on the speed at which the light travels.


By observing the wavelengths of light and their speeds, we can learn the frequency of light that the eyes can detect, the wavelengths that are produced in the air at different times of the day, and the color of light that is produced by the atmosphere and by stars at different times of the night. We can then use these data to figure out what the color of the sky is and why the sky is blue.
