- The reddish color of the sun at the time of sunrise and sunset is due to scattering of light.
- The sunlight comprises of 7 colors Violet, Indigo, Blue, Green, Yellow, Orange and Red out of these Violet has the lowest wavelength and red has the highest.
- In the morning and in the sunset, the sunlight has to travel more distance through the atmosphere of the earth to reach us. So, only the colors having high wavelength reach us and colors with low wavelength gets miss in the midway because of scattering by air, moisture, smoke and other dust particles in atmosphere.

Understanding the Reddish Appearance of the Sun
When the Sun is near the horizon during the morning or evening, it often appears reddish due to the phenomenon known as scattering of light.
What is Scattering of Light?
- Scattering occurs when light waves encounter particles in the atmosphere.
- Different colors of light have different wavelengths; blue light has a shorter wavelength and is scattered more than red light, which has a longer wavelength.
Why does the Sun appear Reddish?
- When the Sun is low on the horizon, its light passes through a thicker layer of the Earth’s atmosphere.
- The longer path length means that a greater amount of shorter wavelength light (blue and violet) is scattered out of our line of sight.
The Role of Atmospheric Conditions
- Factors such as pollution, dust, and humidity can enhance scattering effects.
- During sunrise and sunset, particles in the atmosphere scatter the shorter wavelengths effectively, leaving the longer wavelengths (reds and oranges) to dominate.
Conclusion
- Hence, the reddish appearance of the Sun during these times is primarily due to the scattering of light, which selectively filters out the shorter wavelengths and allows the longer wavelengths to reach our eyes.
This scattering effect is not only a beautiful display but also highlights the intricate interactions between light and the atmosphere.
