If not yellow, what is the true color of the sun? All Pages

KOMPAS.com – Since childhood, we learned to choose the color yellow for painting Sun. Then, add a little orange or red to describe this moment Sun Up or Set.

But the star at the center of our solar system isn’t actually yellow, orange or red.

But mix all these colors together, and more.

The sun emits color light continuously.

If you look through a prism, you will see sunlight divided into red, orange, yellow, green, blue, indigo and violet.

These are all colors in the visible spectrum In the rainbow.

In fact, a rainbow is how sunlight appears to the eye as it passes through droplets in the atmosphere, which act like tiny prisms.

However, although the colorful sun may appear bright, that is not entirely true.

If we mix all the colors of light emitted by the sun, we get only one color.

If we want to know what it is, there are traces in the sky. Fluffy clouds that reflect sunlight are not yellow or any other color.

They are white because that is the true color of the sun.

Why does it look yellow?

Each color in the solar spectrum has a different wavelength.

At one end it has an elongated red wavelength.

The colors then shrink in wavelength, dropping from red to orange, yellow, green, blue, indigo and purple, the colors with the lowest wavelengths in the spectrum.

At short wavelengths, colored photons (elementary particles) are scattered in the atmosphere and appear disorganized compared to long wavelengths.

In space where light travels unimpeded, there is nothing to distort photons, and the sun appears as a ball of white light, the ‘true color’ of our star.

However, as sunlight passes through Earth’s atmosphere, molecules in the air decompose photons of lower wavelengths.

Colors in the spectrum with long wavelengths easily reach our eyes.

“The atmosphere blocks the most energetic part of the light spectrum associated with the UV and blue zones,” explains Angel Molina, who runs the Astronomical Diary website.

“So, like a warm light bulb, the sun sees the earth without the cool colors, which are removed by the atmosphere. It leans towards yellow and gets warmer colors.”

But why in yellow or red or orange, the wavelength is longer?

Gonzalo Doncredi, who teaches astronomy at the University of the Republic of Uruguay, told the BBC that sunlight is in the middle of the spectrum, absorbing colors with lower wavelengths from green to purple.

Is the sun green?

You’ve probably seen posts on the internet or posts on social media that claim that the sun is actually green.

Gonzalo Donreddy said the concept stems from the fact that if we make a color map of the sun’s spectrum, it will look like a mountain with its peak in the green zone.

The human eye can’t tell the difference between the colors of solar radiation, but they have tools that can, and they have detected the color green very intensely.

“But once you remove short wavelengths like blue from the map, the peaks turn yellow,” says Gonzalo Donreddy.

“This detail helps explain why we see a yellow sun on Earth.”

Why is the sunset red?

When the sun rises or sets, it is closest to the horizon, allowing sunlight to pass through more atmospheric molecules.

This causes more blue distortion, allowing red and orange to dominate the sun’s appearance at longer wavelengths.

In fact, the phenomenon has a name, Raleigh Scattering, after the 19th century English physicist Lord Raleigh.

As the sun moves through the sky, its angle to the earth is constantly changing, imparting different colors at different times of the day, including red sunsets.

We hope this article expands on our interesting stellar information, but please keep in mind that you should never look directly at the sun – or indirectly using a telescope or telescope – this may cause irreparable damage to your vision and lead to blindness.
