Sunset In Alexandria, Virginia

Why are sunsets red or orange?


Sunsets often have a red or orange color to them. Why is this? Sunlight (what we call “white light”) is made up of all different colors of light, each having a different wavelength. During a sunset, more red light is scattered toward you because of aerosols in the lower atmosphere, compared to the amount of blue or green light that is scattered.

(Light scattering by different amounts for different wavelengths also explains the color of almost anything: green grass scatters more green light than all other colors of light.)

So why isn’t the sky red when the sun is overhead? Because at sunset (or sunrise) sunlight is passing through a much longer path of the lower atmosphere, which is where most of the aerosols are concentrated. So, the scattering effect of the aerosols is magnified, causing more red light to be scattered than other colors of light.
