Question

Quizplus · Accepted Answer

The redness of the moon during a lunar eclipse is due to refraction by Earth's atmosphere, which causes the long wavelengths of red light to bend and pass through, while shorter wavelengths get scattered. This refraction is caused by the Earth's sunrises and sunsets being projected onto the moon during the eclipse.
