Why are sunsets so many colors if the sun is white?
In: Planetary Science
The sun gives white light, which is all colours of light mixed together. When you shine sunlight through a prism, you get a rainbow, because the various wavelengths that make up white light refract by different amounts.
During the day, the sky appears blue because that’s the colour that gets scattered the most by the earth’s atmosphere. But when the sun is close to setting, the blue light gets scattered away from our eyes, and that way we can see the longer wavelengths like yellow and red.
