Why is the sun red?

The wavelength of light changes from long to short, the wavelength of infrared light is longer than red light, and the wavelength of ultraviolet light is shorter than that of violet light. White light is composite light. Light has wave-particle duality, and the wavelength is short, such as violet light, which is relatively strong and easy to be scattered; Long wavelengths, such as red light, have strong fluctuations and are easy to penetrate dust and fog or other objects.

In the morning or evening, the sun's rays are obliquely radiated, and the distance through the air layer is relatively long, and the scattering is very weak. The most attenuated is purple in the sun's light waves, followed by indigo, blue, etc., and the least attenuated is red or orange light. These faded colored sunlight shines on the sky and clouds, creating a vivid and dazzling rainbow.

For example, when the sun has sunset below the horizon and the sunset on the horizon should disappear, because there are clouds below the horizon, the glow below the horizon can be reflected by the bottom of the clouds, but it can show a piece of carmine, and the more impurities in the air, the closer the color of the sun is to carmine.

There are 7 colors of sunlight, each with a different length of light waves, with red waves being the longest and others being shorter. In the morning and evening, the distance of sunlight through the atmosphere increases, and at this time, the short color light of the light wave cannot reach the horizon, and only the red light passes through the atmosphere to the ground, so the sun we see is bright red.

The reason why you see it is red, because in the morning and at dusk, the air is the most abundant, and the most reflective thing is the red element in the moisture.

In fact, the sun is flame-colored, and it is refracted by water vapor in the atmosphere that it appears red to the naked eye

The sun does not celebrate the fact that the clump is red, but emits a white light with a slight yellowish tinge.

There are tons of dust and tiny water droplets floating in the air, and sunlight is scattered in the atmosphere around the Earth (and air molecules are also at work). The shorter wavelengths of violet, indigo, and blue light are scattered greatly, and they mix together to form the blue sky orange.

In the early morning and when the sun sets, the light obliquely passes through the thick layers of the atmosphere. During such a long journey, most of the blue light with shorter wavelengths is scattered away, and the light that hits your eyes directly is the daylight that has lost its blue light. Therefore, the sun no longer looks so bright, but becomes a big ball of fire, and the color is orange-red.

The sun has a color temperature of 6000K and is white.

The angle of the sun in the morning and evening is smaller than the angle at noon, and the light travels longer in the atmosphere, so too much scattering makes the blue wavelength of light scatter away and leave red light, due to the production and life of the day, the sunset is more dust and impurities in the atmosphere than the sunrise, and absorbs more blue light, so the sunset in the evening is more gorgeous than the sunrise.

The Sun is the central body of the solar system and occupies the overall mass of the solar system. The eight planets in the solar system, asteroids, meteors, comets, outer Neptune objects, and interstellar dust all revolve around the Sun, which revolves around the center of the Milky Way.

The sun itself is a flashpoint, and its structure is there.

Like a luminous nuclear energy body, nuclear fusion is taking place every minute and every second, and with the same version of the time, sunspots are attached to the surface of the sun, and at the same time as the sunspots burn, the sun begins to emit heat, producing a golden red color like a flame. Why the sun is red, it still depends on when the energy in it can be burned out, once the combustible energy disappears, the sun will naturally turn black, of course, we can't see the day, or it will really be the end of the world.

First of all, the sun is not copying.

The reason why the red is seen is the red.

At that time, because in the morning and dusk.

The air is the most abundant in moisture.

And the most powerful reflection is the red element in the water vapor.

Usually we say that sunlight is white light, which is said to be broad daylight, about 8 or 9 o'clock in the morning to 4 or 5 o'clock in the afternoon, in fact, sunlight is not strictly white light, sunlight contains red, orange, yellow, green, blue, purple and various colors of light, of which the composition of yellow light is more, and the total visual effect of sunlight seen by the human eye is a kind of golden white light. However, under the conditions of the rising sun and the setting sun, the sun's light hits the observer's eye, it is oblique, and it passes a longer distance in the atmosphere, at this time, the scattering effect of air molecules on light is very prominent, this scattering belongs to Rayleigh scattering, and its law is that the intensity of scattered light is inversely proportional to the fourth power of the wavelength, and most of the colors of light with shorter wavelengths are scattered, leaving the red light with the longest wavelength, which directly enters the human eye, so we see the red sun.

I'm colorblind.

I always thought the sun was white.

Now I know it's red.

The sun is hot, when you have a fever.

The face must be red, too, hehe...

Because the sun burns all the time.

The light emitted looks like a fireball to our eyes, and of course it will be red, but the sunlight is white.

Because red light is the most penetrating!

It's also about physics.

The wavelength of red light.

It is the longest in visible light!

Previously, the wavelength was relatively short.

Most of it is atmospheric.

to scatter or refract.

Let's go! That's why the sun we see is red!

The sun is not red, because it emits strong light, not only red light, but also other colors, you see the sun back to the morning or evening, that is because the red light penetrates strongly, and when the sun is on the horizon, relatively speaking, the atmosphere through which the light passes is thicker than usual, and the wavelength is shorter, so it is red.
