What color is the sun?
When we were young, we often said ‘yellow’ when asked what color the sun is. Children and adults alike often paint the sun yellow or orange when drawing. So is the sun really yellow? In fact, the true color of the sun is white . So why is it yellow? The reason why the sun turns yellow is because when the light from the sun passes through the Earth’s atmosphere, other blue, As the green and purple scatter in the air, the sunlight that comes to us turns yellow or orange.
In other words, the yellow, Oranges and reds are coming to us more because they don’t spread much in the air. Especially in the early morning and late evening, other colors become more widespread, causing the sun to become more yellowish and reddish.
The Earth’s atmosphere is green with short wavelengths. As it spreads blue and purple, the sun’s rays become more yellowish, and there is smoke and flames in the air. Dust also makes the sun more yellow. Therefore, there is no way to find the true color of the sun on Earth. To see the true color of the sun, go from the International Space Station (ISS), which is currently in orbit around the Earth.
Why is the sun white?
Among the rays emitted by the sun, the colors we see with our eyes are just a tiny fraction of all the radiation emitted by the sun. The rays emitted by the sun (rays emitted in the universe) are called the electromagnetic spectrum. In Myanmar, it is called electromagnetic radiation. This electromagnetic spectrum extends from radio waves to gamma rays emitted by an atomic bomb.
The light visible to the human eye is in the middle of the electromagnetic spectrum (EMS).
If you want to be sure of the light emitted by the sun, the best way is to look through a prism. If you place a triangular glass in the sun, you will see the rays of the sun (visible to the naked eye) split apart. If you do not have a triangle, do not worry. When it starts to rain, go outside and look. If you see a rainbow, you will see the rays of light that will live in it.
The visible rays of the sun are purple, Black Blue Green Yellow Only orange and red. Red has the longest wavelength and purple has the shortest wavelength. When you combine all the colors, you get white.
There are seven colors of rainbow colors
How does the earth’s atmosphere turn the sun yellow?
The main culprit that causes us to see the sun as yellow from the earth is the Earth’s atmosphere. Oxygen in the air When the sun strikes the nitrogen and carbon dioxide molecules, some of the radiation in the sun’s rays radiate sideways. The main wavelengths are short-wavelength purple, Blue, green, and so on. That is why when the sky is clear in the afternoon, the sky is blue.
As these colors spread to the sides, most of them were yellow, orange, and red when the sun came up on us. So when we look at the sun on the ground, it turns yellow.
The color of the sun seen in space
If you were lucky enough to reach the International Space Station (ISS) in orbit, you would be able to see the true colors of the sun with your own eyes. From here, you can see the true original color of the sun, which has not been altered by the Earth’s atmosphere. In the image below, you can see the sunrise shot from the ISS. In this picture you can see that the sun is white even when the sun rises.
Why does the color of the sun matter?
For the average person, the original color of the sun does not matter. But for astronauts, what the sun really is is very important. All the stars in the night sky are the sun or galaxies. Scientists have analyzed the light from these stars and studied its internal wavelengths. The star can be categorized according to the colors it contains. The composition of the star (composition) depends on the amount of light involved. They can determine the age and life of a star.
The star’s temperature can also be determined by looking at the color of the star. For example, the temperature of red stars is lower than that of white stars. Red stars have a temperature of about 3,500 K (3,800 ° C). White stars like ours have a temperature of about 5,800 K (6,100 ° C). The hottest stars are blue and have temperatures above 10,000 K.
