- And because red has the longest wavelength of any visible light, the sun is red when it’s on the horizon, where its extremely long path through the atmosphere blocks all other colors.

How does the Sun become distorted when viewed on a distant horizon?
When the sun is near the horizon, it the path of the light through the atmosphere (and in particular through layers which have a higher concentration of dust particles) is longer, thus the scattering away of the non-red components is more pronounced.

Aug 22, 2023 · The sun at the horizon turns red because the blue light is being scattered by the atmosphere (contributing to blue skies for the day side of the world), and the red passes straight through. Consider if the sun produced only red light -- then you would see no additional reddening near the horizon because there's no blue light to remove from it.
Jul 18, 2018 · When the Sun is low on the horizon, rays of light shine back up onto the underside of cloud high in the sky, reflecting back those bright orange and red colours that make it look as if the sky has turned to fire.

Sunrises, sunsets, moonrises and moonsets are excellent opportunities to capture a particularly beautiful photograph. When you see them near the horizon, the sun and the moon can look distorted in the most fascinating ways. Their edges may appear jagged. Their bottom areas may flatten out or shrink into a pedestal. Nearby clouds and twilight color ...
So we know there’s more air in the direction of a horizon. Now consider all the different ways refraction affects a sunrise, sunset, moonrise or moonset. But it’s not only the amount of atmosphere that plays a role. There’s also the pressure, the temperature and the humidity. They all affect the air densityand thereby how much light rays will be be...
The bending of light rays in this manner is known as atmospheric refraction. Without any kind of disturbance, light would travel in a straight line, and give your eye a true image of what you see. For objects with a small angular size – like stars – atmospheric refraction causes them to twinkle morethe closer they are to the horizon. But what about...
When atmospheric refraction is at its most extreme, you might see a mirage. It’s the exact same situation, the light is bent and distorts the image. But here it can be refracted so much that there’s a mirroring effect and you will see drawn out or multiple images. Or it may show displaced images so the moon appears higher on the sky than it actuall...
Additionally, light of different wavelengths reacts differently. For example, blue light (which has more energy, a shorter wavelength and higher frequency) is more affected by refraction than red light. That means red colors have a larger chance of coming through to you than blue. That’s why sunsets, sunrises and the moon appear redder near the hor...
Bottom line: The amount of atmosphere between your eye and what you observe determines how much distortion you will see. This phenomenon – atmospheric refraction – is why the sun or moon may appear flattened near the horizon.

However, at sunset, light has further to travel through the atmosphere. The shorter wavelength blue light is scattered further, as the sunlight passes over a greater distance, and we see the longer...
Nov 6, 2007 · This is why sunsets are often yellow, orange, and red.” And because red has the longest wavelength of any visible light, the sun is red when it’s on the horizon, where its extremely long path through the atmosphere blocks all other colors.
Apr 28, 2024 · Why the sun and moon can appear red closer to the horizon. Have you ever noticed the color red showing up at sunset and sunrise? Here's why.
