If You've Seen a Green Flash in the Sky at Sunset, Here's Why

 The atmosphere acts as a prism, and it's all about light. We see blue sky because of Raleigh scattering ( scattering light from the sun into much smaller wavelengths. We see red skies as sunlight filters through pollution. Now, here's the explanation for why sometimes we see green flashes at sunset.

WHY DO SOME SEE A GREEN FLASH FROM THE SUN?    The green flash is a phenomenon that occurs at sunset and sunrise when conditions are favorable, and results when two optical phenomena combine: a mirage and the dispersion of sunlight. As the sun dips below the horizon the light is being dispersed through the earth's atmosphere like a prism. The effect is caused by layers of the Earth's atmosphere acting like a prism.
