Why is the sunset red⁉️
Red light has a longer wavelength than blue light.
This means that when the sun sets and is low on the horizon, the sunlight has to pass through more atmosphere than it does when the sun is directly overhead.
As the sun sets we see red, orange and yellow light because the blue light has been filtered out by the thicker layer of atmosphere.
