Why is the sun red: Early morning or late evening, an orange or red Sun is a sight to behold. Rayleigh scattering is a phenomenon that causes the sky to take on these vibrant colors.
Made of Various Colors | Why is the sun red?
Visible sunlight is a form of electromagnetic energy released by the Sun. The visible light, also known as visible light, seems white but is made up of colors with varying wavelengths, with violet having the shortest and red having the longest.
When you gaze through a prism or view a rainbow in the sky, you can see the distinct colors.
The Atmosphere of the Earth | Why is the sun red
The majority of the Earth’s atmosphere of gas molecules, with oxygen accounting for around 21% and nitrogen for 78%.
In addition, the atmosphere contains water molecules in the form of droplets, ice crystals, and vapor, as well as particles such as dust, pollution, and ash, which are denser closer to the Earth and thin out as altitude increases.
The Sun Is Yellow, And The Skies Are Blue
Light of longer wavelengths, such as red, yellow, and orange, easily flows through gas molecules like nitrogen and oxygen.
In contrast, light shorter wavelengths, such as blue and violet, are absorbed and dispersed in all directions by the gas molecules.
The color is scattered blue and violet light reaches your eyes when you look up at the sky during the day; however, the human eye is more susceptible to blue than violet frequencies. Thus the sky appears blue.
Rayleigh scattering is the name for this fact. It was named after John William Strutt, also known as Lord Rayleigh, a British physicist. It is also why, even though the sky is blue, the Sun seems yellow during the day, even though the sunlight is white.
Light needs to travel a shorter distance through the atmosphere when the Sun is high in the sky.
It means that most yellow, orange and red light goes through, but a small portion of blue and purple light is scattered and removed. As a result, the Sun seems yellow to us on Earth.
Traveling a greater distance
When the Sun is close to the horizon at sunset and sunrise, sunlight must travel a greater distance and pass through a more dense environment to reach an observer’s eye.
Most light of lower wavelengths – blue, violet, and green – is dispersed numerous times due to Rayleigh scattering, allowing only longer wavelengths – red, orange, and yellow – to travel straight through to the observer.
It is why the Sun takes on stunning red, orange, and yellow hues as it rises and sets.
Pollution and Dust | Why is the sun red
The air quality influences the color of sunrises and sunsets that sunlight must pass through. Dust particles and pollutants tend to dull the sky’s colors and prevent light from reaching observers on the ground.
When the air is full of Dust and Pollutants, the sky takes on drab red and yellow colors as a result.
It is why sunrises and sunsets in rural locations, over the ocean, and deserts are far more bright and colorful than those in towns.
The Moon Is Red | Why is the sun red
During lunar eclipses, Rayleigh scattering is also responsible for the Moon’s reddish or orange color. The quantity of pollution and dust from storms and volcanic eruptions in the Earth’s atmosphere can influence the shade of red the Moon takes during the eclipse.
