"The Green Ray"

"The Green Ray" is a natural optical phenomenon where, at sunset or sunrise, a brief green flash appears just above the horizon. This occurs due to the Earth's atmosphere acting like a prism, separating sunlight into different colors. Typically, the green light, being slightly bent or receptor-specific, becomes visible for a moment before the sun fully sets or rises. The phenomenon is rare and often observed over large bodies of water. It also features in literature and film, symbolizing hope or a fleeting moment of beauty. Physically, it is a well-understood atmospheric effect involving the dispersion of light.
