How Does the Composition of the Atmosphere Contribute to the Red Sunset?

How we perceive color is fundamental to understand why sunsets are red. It’s all due to the atmospheric conditions and composition. Colors are merely the reflection of light on different surfaces. That’s the reason we can see different colors depending on the object where light is reflected.

When you see a prism, you can see that it’s made of tons of different colors. Even the light that sometimes looks white to our eyes is more colorful than we can imagine. The same happens with the atmosphere and how light goes through it. As we know, the sun is low in the sky at sunset and sunrise.

Light goes from the sun through the atmosphere at all times. At sunset, the sunlight has already gone through a thick amount of atmosphere. Because of that, light tends to be scattered and deflected to many points before getting to us.

That process leaves only yellow and red light to be perceived by the human eye. Considering that, we could say that the thickness of the atmosphere and the low level of the sun at sunset is what makes it red.

In a nutshell, the light travels a greater distance at sunset, which makes us see the red and yellow in the sky. That can change depending on the weather conditions and the pollution of the place. Some countries have sunsets of different colors, including pink and even purple.

The Appearance of a Red Sunset 

As we mentioned before, sunsets can look very different depending on the weather conditions. Due to that, their colors change drastically. However, the most popular type of sunset is red sunsets. Their appearance can also change depending on where you see them from.

When it’s almost night, sunsets are followed by a considerable number of dark clouds and a bluer sky. Yet, when the sun is just setting, the sky tends to look orange, with almost no clouds left to be seen.

You could say that sunsets look like sunrises. However, the former looks orange and red. Sunsets only last a few minutes. Considering that, pay attention to the sky if you are planning on seeing them with someone.

Facts About the Red Sunset

Taking into account that sunsets can be different depending on where you are, there are also many facts and things to understand about them.

As you may have noticed by looking at the sunset, the sun loses color when it begins to set. At first, its wavelengths go to green and yellow colors, getting to the orange and red shades we all know. That makes the sun look bigger and more colorful than ever by the end of the sunset.

The view of the sun setting is just an illusion, though. You can understand that by reading what we said about the composition of the atmosphere and the light that goes through it. We don’t technically see the sun setting, but a refraction of the sunlight.

In reality, the sun has already set on the horizon when we start seeing its orange colors.

While many people think pollution makes sunsets more difficult to notice, it happens the opposite. The pollution displays smoke particles that look pink and purple all over the sky. Even if this looks beautiful in some places, it’s a bad thing for the environment.

Many people think sunsets and sunrises always happen at the same time. That couldn’t be further from reality. The timing of these events changes throughout the year. Additionally, the sun takes different paths to set and rise every day.

That doesn’t mean the sunset can happen three hours later in one month. The timing change tends to be of instants, so it’s hard to perceive.

Speaking about things that are hard to perceive, not everyone knows that the sunlight is white. As we mentioned earlier in this article, the light that goes from the sun to the atmosphere has no color at all. Because of that, we only see the refraction of light on different surfaces.
