Question

Quizplus · Accepted Answer

Red sunsets occur because when light travels through the Earth's atmosphere, the shorter blue and green wavelengths are scattered more due to the higher air density, and therefore do not reach the observer. However, the longer red wavelengths are not scattered as much and are able to reach the observer, resulting in a red-colored sunset. This means that the longer red wavelengths have survived being scattered in the air.
